Just did my oil change. Trying Royal Purple this time. I will see how it goes. Any experiences you could share? I tried motorcraft and mobile1 already.

I don't think you will notice any difference in how the car runs, but your engine will love you for it. I know they have done comparisons between different types of oils and RP seems to come out ahead and they claim to help with HP. Not cheap, but you get what you pay for.

After spending all my money on my built motor it is what I use.

Gotta built motor too and I swear by Motorcraft semi-synth, can't beat price price/quality. Purp stuff is overpriced and overrated IMHO!
