I just have a question. I have been putting Royal Purple in my car for awhile now. and i was wondering what anyone thought about Leading Edge? http://www.modernperformance.com/all/lubricants.shtml
Modernperformance has it on their website. and i was wondering if anyone has tried it or what? Or should i just stick with RP!

 

id say stick with the rp ive heard nothing but good things about rp and know plenty of people who use it. personally myself i still use the recommended oil change mobile 1 all around, but that will change once my agp s4 is put in, i am starting to install it hopefully this weekend.

 

Oh you lucky SOB im still waiting to save up for that. So im pretty sure im sticking with RP. ive used it since my mustang lol. But i want AGP S4!
