which line would u use for our moded truck. the standard oil or the xpr?>

 

Depends on the extent of the mods. Unless you have upgraded cams (206/212) not worth the extra per qt. cost($6-$7) for the regular synthetic compared to $11.50-$12.50 per/qt for the XPR.

 

Go with the RP. That's what I put into my truck. I still haven't gotten to my second cycle yet though.

 

are you using the regular oil

 

I'm using the regular 5w30 RP.

 

do u feel a difference with royal purple?

 

I noticed a slight difference with RP, but like I said, I haven't hit the second cycle yet. Supposedly the second cycle is where you feel the difference. The problem is, the cost, even though you'll spend that much on a quart of oil if you change your oil every three months.

 

I agree with DakotaStone. I'm still on the first cycle as well but will stay with it long term.

 

i dont go by every three months,every 3k milesbc i dont drive alot. mostly around town
