A. It takes thousands of hours of engine dynamometer testing to qualify new products against these demanding test standards. But at Chevron, we understand that true proof of performance can only be demonstrated by exposing our products to real life customer demands – on the road, on the farm, in the heat of summer and the dead of winter. Chevron and our partners have been testing new PC-11 engine oils in a variety of equipment, both on-road and off-road, to further demonstrate the performance benefits of these new products so that you can be assured they’ll stand up to the rigorous demands of your fleet’s operations. In fact, this is the most rigorous testing program we have ever conducted for an engine oil category change.
