| I think it's BS. If putting motor oil in your coolant helped the system, then the car manufacturers would do that. But they don't. Besides, oil and water don't mix. Also, if his Blazer doesn't have such a high compression ratio to warrant 94 octane, then using it isn't doing anything but draining his wallet. And his logic for using Bosch? Lame. Ford was the first company to use an assembly line to mass produce cars, does that mean that we should only buy Fords if we're looking for a mass produced car?
