Royal Purple. Engine Damage In The Long Term?

deuce189

I really don't see it as much better than the other, I've always used mobil one synthetic in all of my vehicles even in my integra GS-r back in the day changed it ever 4k, the engine hydrolocked and had to be pulled and rebuilt. The car had 140k miles on it, always ran mobil one synthetic. My mechanic was amazed that there was not a bit of sludge in the engine other than normal discoloration from and wear from any high mileage vehicle, every thing was coated nicely. Same with my STI when i pulled the stock block for the new built one, always ran mobil 1 synthetic changed every 3.5-4k miles, pulled the heads and the engine still was in very very good shape at 70k miles. I didn't rag on the car but i didn't grandma on it either. Sold that long block to a guy without any complaints or news of it giving him problems.

Anywho, long story short. Mobil 1 Synthetic is great IMO and is very good for the generic. I think people mainly buy stuff like redline or RP for the name. Not saying they don't have that bit of extra for racing purpose, but i personally don't think it far exceeds much over anything else. It's all relative if you ask me.
