iv read some other threads.. still have a question bout royal purple
 

i talked to my bro who owns a beast a rsx turbo pumping out 470 hp ... i asked him bout royal purple.. he said he can not use it in his car... says it doesn't like it... has anyone had any issues with royal purple and their 370z ?

i use it, no issues thus far.

thanks anyone else use it?

I've used it in many cars, including my TT gto. Did your bro give you any reason he cannot use this oil, or why he doesn't like it?

i think he said when u got a 4 cylinder .. thats been modded like that .. its relay picky i don't know ill ask him again i went from a corolla to my Z so im starting to learn :) :happydance:

?

I am not too sure about Royal Purple I have heard about the Viscosity breaking down... one of which is the company my father works for they use it in their trucks and he said they have had nothing but engine problems related to the oil... wether thats true or not its enough for me to stay away from it..... I used mobil 1 syn. in myt 06 350Z and this time im going to use Amsoil in the 370Z

Dumped the factory oil at 1,000 miles filled it up with Royal Purple 5 W 30 and will continue to do so every 3,000 miles religiously.

Fantastic Oil.

I don;t know what the weather has been like this summer in Memphis, but around here it's been above 100 for now 63 days this summer so far, set to break a record.....one I could easily do without, but the oil is holding up extremely well in the heat.

I dont know what your brother's issue is, but RP rocks. IMHO, probably the 2nd best mass produced oil on the market.

What's number one? Redline Motul...?

Last sentence of the paragraph sounds in order of popularity, from what I've read over the years.

Best Motor Oil - Synthetic Motor Oil - Reviews of Motor Oil - Castrol - Kendall

Well popularity doesn't mean best necessarily. Burger Kings sells lots of burgers, but they aren't the best.

I been using RP for about 1500 miles so far in my 370Z. So far so good.

I agree! I use RP, because a highly intelligent individual from my previous site recommended it for every day driving.
