this is from the makers of royal purple. they make synthetic oils for high performance machines. this product here will make your engine run 25 to 44 degrees cooler then normal oil.

also for you car freaks as myself, they have a synthetic oil that will give you on average 8hp gain from just swapping all fluids.

just thought id let you know. this is what i'll be using on my turbo mr2 and r1 very soon.

 

you ever used it in your bike? i'm thinking about switching to synth after the bike hits 5k miles

 

i use mobil 1 car oil and it give me about 10hp...hahaha....j/k but i do use mobil 1 car oil in my bike ran it now for about 1500 and no problems...i also use a car oil filter...raul can chime in on this one

 

Shell Rotella. All the way for my bikes, diesel, and car. Offered in Dyno or Syth and can get it at Wally in gallon jugs.

For oil filters save some money and cross reference as said above

Motorcycle Oil Filter Cross Reference

 

Raul, whats the deal with using a car filter?

 

I'm a big support of Amsoil.

 

you dont get the ass raping due to a cool logo stamped on the side that has your motorcycle manufacturer's logo.

actual there is a big report raul posted a while back that states the car filter actual has the best break down of sludge and what not compared to motorcycle and other leading car filters....i use the pure puraltor pure one filter the 3.5 i have had no problems at all i was worried at first using car oil in my shit but have had no problem what so ever....actual it quited my motor down....i wish i still had the survey that raul sent me.....it was really interesting and showed no difference between motorcycle oil and car oil...

 

awesome data charts. That may just convince me to switch over to Amsoil. The scarring data for Royal Purple ain't too hot eh? BTW, who published this study?
