Does anybody know much about chevron oils?? Its an American company.Every time Im at my local costco I am tempted to buy some.Its about £9 or something for 5-40 fully sythetic!.Ive compared the bottle with other products and it falls under the same specs.I mean all oil has to confirm to a certain specification right? so it should be fine. Chrysler use chevron like Renault use Elf. The only thing I would say is they change there oil a lot more often in the states... my wife is American and has a car over there... they do an oil and filter change every 3000 miles.This is a standard service interval from the manufacturer... even foreign cars as she has a Hyundai.But then again when an oil and filter change only costs you £12... including the oil and filter!!!! I can see why you can change it every 3000.Anyway back to the question I was asking... as most of us change our oil pretty often anyway, wouldnt this be a really cheap deal on fully synthetic???
