Do any of you fellow Honda owners use Royal Purple oil in your engines? I have checked out their website. It claims to outperform all other brands of full synthetic oils. It appears to be favored by those who build racing engines because of its ability to significantly reduce wear. Friction leads to wear, it also affects gas mileage. We all know that most Accords, when properly maintained can turn out some good gas mileage; so if any of you guys are using Royal Purple, have you noticed further improvement in gas mileage?

 

I don't use it in my car but i do in my 350 in my truck and in the rear end but that thing sucks so much gas that i cant tell anything.

Look in the UOA section or use the search feature. It appears that it's good but not great. For the price I'll stick with Mobil 1.
