Letter Final Report titled, "Fuel Volatility Trends", performed 

under Contract 68-03-3192, Work Assignment 4, Task 3; Identified 

as SwRI Project No. 03-7774, Phases -304, -314, and -324. 

I. INTRODUCTION 

This task of Work Assignment 4 was an attempt to determine how 

gasolines with a range of front-end volatilities "weather" in the fuel 

tank during normal consumer use. Two vehicles, a Mercury Marquis and a 

Ford Tempo, were chosen to represent different fuel tank volumes and fuel 

consumption rates. Three fuels with various Reid Vapor Pressures (RVP of 

approximately 9.0, 10.5, and 12.0) were evaluated to represent both summer 

and winter grade gasolines. Vehicle evaluations began with a full fuel 

tank in each case. After about 50 miles of vehicle operation, the vehicle 

was parked and left to soak overnight. The next day, a fuel sample was 

removed from the fuel tank for analysis of RVP and boiling point distribution. This procedure was followed until the fuel tank was nearly empty. 

Results of the fuel analyses were compared to vehicle miles driven, time, 

and vapor volume remaining in the fuel tank. 

II. SUMMARY 

For the test procedure used, the vapor volume, miles driven, and 

time were shown to be related to each other. Both vehicles responded 

similarly to the test procedure. In general, the RVP decreased an 

average of 9 percent as the fuel in the tank was consumed (or vapor 

volume increased), independent of the fuel tested. This reduction is 

based on a relatively constant vehicle mileage per day and fixed time 

period for soak. There was some indication that when the vapor volume 

is large, additional soak time may further reduce the RVP.

III. PROCEDURE 

2 M\, • wr 

Two vehicles were chosen by the (then) Project Officer Mr. Robert 

J. Garbe. These vehicles were a 1984 Mercury Marquis and a 1984 Ford 

Tempo. These two vehicles were considered representative of fuel tank 

capacity and fuel consumption for typical vehicles on the road. Complete 

descriptions of the two test vehicles are given in Table 1.

Evaporative emission tests were performed on the Tempo and Marquis using 

Amoco Indolene motor fuel. Properties of this fuel are given in Table 2. 

The Tempo's evaporative emissions were 1.66 g HC. This value falls below the 

2 g standard. The Marquis did not initially pass the evaporative test. In 

fact, the evaporative emission test was abbreviated after the diurnal 

breathing loss portion yielded 11 g. Investigation into the cause for 

failure indicated a poor-sealing gas cap. Another evaporative test was 

performed, and again the Marquis failed due to the excessive (2.26 g) hot 

soak losses (HSL). Further investigation using a HC analyzer and probe 

indicated that the source of the emission was the fuel line and clamp just 

before the carburetor. A larger-than-required rubber fuel line had been 

installed and forced to clamp down on the fuel line. As the fuel tank 

pressure increased, fuel vapors leaked past the clamp. The correct rubber 

line was installed, and the evaporative test was performed with acceptable 

results. Results of the evaporative tests are shown in Table 3 along with 

the associated FTP emissions. Computer printouts for the emission tests 

are located in Appendix A, pages A-2 through A-5. 

The fuel described in Table 2 was used as the first fuel for test 

based on its RVP of about 9. The second and third fuels for test evaluation were to be commercially-available unleaded gasolines. One locallyavailable unleaded gasoline had a RVP of 10.0. With Mr. Garbe's approval 

this gasoline was doped with n-butane to increase its RVP to 10.5, in

order to meet the second test fuel requirement. Additional n-butane was 

added to another batch of the same 10*0 RVP fuel to raise the RVP to 12.0 

as required for the third test fuel. All fuels and fuel samples were 

stored in a "cold box" (about 60°F) until ready for fueling or analysis. 

The procedure used to evaluate each fuel is presented in Table 4. 

Each fuel sample withdrawn was coded for ease of identification. The 

sample numbers describe the car, fuel, run, and test point as follows: 

1st digit = car: 1 for Marquis, 2 for Tempo 

2nd digit = fuel approximate RVP: 09, 10, or 12 

4th digit - run number: 1 or 2 

5th digit = Test point: 0 for sample during fillup, 

1 for first sample withdrawn after 50 

miles driven and 24 hr soak, 2 for second 

sample withdrawn after an additional 50 

miles driven and another 24 hr soak, 

same pattern for 3, 4, and 5 

Example: 

20913 means: Tempo, fuel with 9.0 RVP, first run, 3rd sample 

withdrawn 

The percent vapor volume for each vehicle was calculated using fuel 

tank capacity, sample extraction volumes, and the fuel economy values 

obtained during a "3-bag" FTP (obtained during the evaporative emissions 

screening test). Fuel tank fill capacities were measured by fueling the 

vehicles to the top of the filler tube while rocking the vehicles 

slightly. These measurements (18.0 and 15.5 gallons, respectively, for 

the Marquis and Tempo) indicated the maximum volume of fuel that could 

be put into the tank during evaluation of the test fuels. The vehicle 

was then raised with a floor jack so that the tank filler tube was the 

highest point in the system. The additional amount of fuel added was 

measured, and considered to be the vapor volume of the fuel tank when 

the tank is considered "full" of fuel. In both vehicles, this vapor 

volume was approximately 2 ounces; or about 0.1 percent of the entire 

volume of each fuel tank. 

Fuel consumption during mileage accumulation was calculated by 

applying the EPA "fuel economy estimate for labeling factor" of 0.9 

(for FTP, per Federal Register) to the "3-bag" FTP exhaust emission test 

fuel economy value. The volume of each sample removed also was considered. 

The percent vapor volume was calculated using the equation below: 

total miles driven total gallons of fuel 

Vapor Volume, % = [ mPg * °-9 removed for samples 

total tank volume, gallons 
P.6 

TABLE 4. PROCEDURE FOR FUEL SAMPLING AND MILEAGE ACCUMULATION 

ON MARQUIS AND TEMPO 

1. Remove fuel from fuel tank by pumping as much out as possible. 

2. Add about 1 gallon of the test fuel. Test fuel should always be 

stored in cold box. 

3. Repeat Step 1. 

4. Fill fuel tank with test fuel. After tank is filled, fill 1/2 gallon 

sample can. Tag sample can with correct label. See Bruce Bykowski 

for information. 

5. Park vehicle in designated shaded area. Record odometer mileage and 

date on data form next to correct sample number. 

6. Driver will drive the Marquis first. Only one lap (10 legs) of the 

MVMA driving course is to be driven. The Marquis is then to be 

placed back in the designated shaded storage area for about 24 hours. 

7. Driver is to drive the Tempo next. Same procedure as Step 6. 

8. The next day, before the driver starts vehicle, remove 1/2 gallon 

sample from each vehicle's fuel tank and label sample can with proper 

sample number (see data form). In addition, record date and odometer 

on data form. 

9. Repeat Steps 6, 7, and 8 until there is insufficient fuel in the fuel 

tank to allow for another run on the MVMA driving course. 

10. See Bruce Bykowski to obtain next fuel for test. 
P.7 

The vehicles always were soaked in an outside, shaded area. Only 

during mileage accumulation were the vehicles exposed to direct sunlight. 

If the vehicle could not be tested on consecutive days, it was stored 

inside an air conditioned building (76°F) to minimize temperature effects. 

The ambient temperatures at which the vehicles and fuel were soaking during 

each 24-hour period were recorded. 

Originally, a one gallon fuel sample was to be withdrawn at each test 

point for analysis; but extracting a one gallon sample from the Marquis 

would have reduced the available fuel for mileage accumulation to the 

extent that only a few test points would be available. It was determined 

that at least 6 test points would be needed to meet the original contract 

test plan requirements. Therefore, 1/2 gallon samples were removed for 

analysis. Removing 1/2 gallon samples from the Marquis yielded 6 test 

points, but 7 test points resulted on the Tempo (i.e., another day's 

mileage accumulation could be performed to reduce the fuel in the fuel 

tank). It was considered desirable that for consistency purposes, both 

vehicles should be subjected to similar mileage accumulation, soak periods, 

similar increase in percent vapor volumes to compare the effects of fuel 

tank capacities and other vehicle hardware differences. After the experience 

gained from the first run with the first fuel, subsequent sample removals 

were 1 gallon for the Tempo and 1/2 gallon for the Marquis. This resulted 

in the same number of samples reflecting similar vapor volumes subjected 

to identical driving and soak conditions. 

IV. RESULTS 

After each fuel was evaluated, a sample of the Amoco Indolene was 

coded and submitted for analysis in order to obtain statistics on the 

variability of the analytical procedures. The results of these periodic 

checks are given in Table 5. If it is assumed that covariance exists 

between all three fuels analyzed on the same instrument and procedure, 

then the standard deviation determined from running the base fuel (Indolene) 

periodically can be applied to other fuels to determine confidence limits 

(for 95% confidence limit, X ± 2s). 

The test results for each vehicle, fuel, and run are presented in 

Tables 6 through 11. Tables 12 and 13 present the averages of the 

individual runs for each vehicle and fuel. Reductions in RVP were associated with increased vapor volumes independent of the fuel or vehicle. 

Typically, a 9 percent reduction in RVP was observed. These reductions can 

not be explained by analytical procedure variability as shown in Table 5, 

and therefore are probably real. In some cases the lower boiling points 

of the distillation support a loss in some light ends, but these trends 

may only reflect variability in the distillation procedure (Table 5). 

For the most part, the fuel test sampling was performed on consecutive 

days. This procedure exposed the remaining fuel in the tank to the associated percent vapor volume for only a 24 hour period. During the first 

run on the first fuel, Table 7, when the mileage accumulation and fuel 

sample extraction volumes were being finalized, the Tempo had to wait 4 

days before the last fuel sample was removed. During these 4 days the 

percent vapor volume was 99 percent (i.e., fuel tank almost empty). In 

comparison to the repeat run on this fuel (where only a 24-hour soak

occurred), the RVP associated with this test point was considerably 

lower and several of the distillation boiling points were higher (e.g. 

RVP reduced from 8.03 to 6.28, IBP increased from 92 to 102°F). Three 

out of the four soak days were indoors at 76°F. Only on the last day 

did a 24-hour outside soak take place. 

A similar situation occurred during the second run with the first 

fuel on both vehicles. A 4 day time period occurred between two test 

points. These test points, shown in Tables 6 and 7, occurred between 

41 and 59 percent vapor volumes (i.e., fuel tank about one half full) . 

A marked reduction in RVP was not noticed between these two points, 

even though the soak period and conditions were similar to the first 

run at 99 percent vapor volume. From this limited data, it might be 

conjectured that a large vapor volume in conjunction with an extended 

soak period (not necessarily high ambient temperatures) will yield the 

greatest reduction in fuel RVP. 

The data in Tables 6 through 11 were subjected to a bivariate 

correlation procedure to yield Pearson correlation coefficients. Based 

on the raw data, it appeared that both vehicles responded similarly to 

the weathering procedure, and therefore, data from both were combined for 

each fuel. Combining the vehicle data resulted in a larger population of 

test points, and therefore, a better representation of the weathering 

effects independent of the vehicle. Computer printouts of the Pearson 

correlation coefficients for all variables and each fuel are located in 

Appendix A. As expected, percent vapor volume was highly correlated 

with time between test points and miles driven. Therefore, comparisons 

between percent vapor volume and fuel property changes would be similar 

if time or mileage were substituted for percent vapor volume. Table 14'

contains some of the Pearson correlation coefficients extracted from the 

complete printouts in Appendix A. Coefficients less than 0.70, corresponding to a squared correlation coefficient of <0.49 (i.e., <49% explained 

variability), would not be considered to represent any significant trends. 

For the most part, only RVP shows any potential for a relationship with 

percent vapor volume. As the distillation boiling points increase, the 

correlation coefficients decrease.

Scattergrams were run on all fuels and vehicles for a variety of 

variables. Most of these scattergrams were run in order to graphically 

show the dispersion of test points around a line drawn to best fit the 

data. The fit of the data to that line is reflected by the Pearson 

correlation coefficient. The data set plotted on each scattergram is 

coded for simplicity, and is easily identified. For example, the data 

set identified as "group MAR09R2" means Marquis (MAR), fueled with RVP 

of approximately 9 (09), and the test was the second run (R2). Scattergrams for RVP of the three fuels versus percent vapor volume are given 

as Figures 1 through 3. Figure 1 clearly shows the point where an 

extended soak time in conjuction with a high percent vapor volume in the 

Tempo's tank, yielded the lowest RVP. This single point affected the 

linear fit of the data as reflected in the correlation coefficient. 

Figures 2 and 3 also show a good fit of the data. Figures 4 through 8 

are scattergrams of IBP, 5, 10, 15, and 20 percent distillation points 

versus percent vapor volume for the first fuel. As the distillation 

point (percent of fuel distilled) increased, the scatter of the data 

increased. This result would be expected if it is assumed that weathering would reduce the presence of the light ends while the heavier ends 

remain essentially unaffected. Similar trends were noted for the other 

two fuels. For the other two fuels, scattergrams for these boiling points 

are located in Appendix A. At the request of the Branch Technical Representative Mrs. Amy Brochu, scattergrams of RVP, IBP, 5, 10, 15, and 20 percent 

boiling points versus miles traveled are presented in Appendix B, and these 

same variables versus days (soak time) as Appendix C. 

V. RECOMMENDATIONS 

Based on this limited study and statistical analysis, it appears that 

fuel does indeed weather in the fuel tank. Most noticeably affected is 

the fuel RVP. To a lesser degree, some changes in IBP and perhaps the 5 

and 10 percent boiling points may occur. One area that needs additional 

investigation is the effect of time versus percent vapor volume. Another 

area for possible investigation would be to determine if vehicle operation 

and fueling levels have any effects on RVP changes.
