Hi Guys,

My RX is running 450hp with TD06 and runs hard on the track in temperatures in winter at minumun 16'C and summer maximun 30'C.

I am looking at Royal Purple 10w40 on next oil change, is this the right way to go?

Thanks for any help.

Most track guys run 20w50....stay away from 10w40.

 

How many oils are available on the market? That's how many opinions you'll get. I run 15-50 Mobil 1 Syn (they don't have a 20-50). I may switch to Valvoline 20-50 Race though, just because it's cheaper and I like to change oil a lot. A 20-50 though is the most popular weight choice.

 

Cool thanks for the info guys. Going Royal Purple Racing 51 (20W50)

 

sythetic is pretty much a must in my book. Royal purple will do fine. i run Mobile 1 just cause it is cheaper.
