10 easy HP extra?
A friend has a dyno shop. During a week long dyno rental of a modular engine, the company that was paying the rental found they gained 10hp just by using Mobil 1 oil.
I'm not trying to sell anything. I'm just passing on info.
He also said that the trick way to gain another 10hp is by using a 1" spacer between top of carb and air cleaner.

ive ran penzoil high mileage, mobil 1 full synthetic, and rotella T diesel oil in my 300 since i bought it
the penzoil high mileage and penzoil filter did nothing, the mobil 1 full synthetic with wix filter saw decent improvement, but the biggest difference i saw was going from the mobil 1 to the rotella T diesel oil with a wix filter
so yes mobil 1 full synthetic does help in the 300 but diesel oil works better

Rotella-T is great in my truck, too.
But, want a 10 easy horsepower... use a good flowing intake filter and open up the exhaust. There's ya 10+ hp. By 'open up the exhaust', I mean climb up under it and get creative ;-)

I hear both good and bad about these, and it seems even qualified engine experts disagree on what these things actually get you.

F-250: The only way to determine gains if any for your engine would be dyno pulls. Comparison to the V8 just is not valid.
I've used carb spacers but on a DP manifold with deep ports I don't think there is anything to be gained and I don't use one now. I do use a 3" spacer between the carb and air cleaner. IIRC, Vizard recommends a minimum 3"clearance between the top of the carb and the lid of the air cleaner to improve air flow by reducing turbulence around the top of the carb. Gains, if any would have to be verified with dyno pulls.
