With Jochen Rindt signing for Lotus for 1969, Oliver switched to BRM. He was to suffer disappointing two years at the Bourne team, which would effectively kill off his Grand Prix career. In two years, he would muster just four finishes, with his only points scores being sixth place in the 1969 Mexican Grand Prix, and fifth in the 1970 Austrian Grand Prix. However, in 1970, he led much of the Race of Champions holding off Stewart and was a strong third for most of the Dutch and British GP. The poor result in the Austrian GP which Team boss, Louis Stanley thought he should have won, saw the best car go to Pedro Rodríguez from then on, but Oliver still led some laps at the slipstream Italian race. Stanley described Oliver, as 'good, but not nearly as good as he thought'. The majority of his other races saw the BRM break down. Most pundits and sponsor, Yardley, were surprised and disappointed after Oliver was sacked by BRM. Jackie Stewart, judged Oliver a very good GP and Can-Am driver.
