Hey, has anyone out there tried Royal Purple on their rides? If so, what if any difference, positive or negative did you experience. I'm thinking of making the switch on the next oil change. However, I don't want to waste my time and my ride'* performance if it sux.

Most of us Prefer/use Mobil1. I think it'* a little cheaper, and it helped my engine some. It'* smoother, has less chatter, and oil pressure is good.

I think any synthetic is good, just find one that'* priced well in your area.

Don't waste your money. Stick with the Mobil 1.

I use Penzoil synthetic without any problems at all.

I use Valvolind MAX LIFE... I haven't heard of anybody using valvoline in their bonne'* is there something wrong with it?

I used to, but Mobil1 is rated so much higher, I switched.
