im not sure what oil to use next...i passed 6000 miles already and i want to try something new and better..i been running Royal Purple 5w-30 for a while even with my old S2000 its been gr8t no complains..i have the HR engine..ive browsed through the HR oil analysis thread but still clueless which to use....any suggestions? Thanks

 

amsoil 5w20 for me for once a oil changes.

 

After reading the UOA thread by Resolute for a few weeks I narrowed it down to:

Shell rotella 5w-40 t-syn (good bang for the buck - good uoa numbers and under 20 bucks a gallon. Found at walmart and autozone.)

Castrol GTX: (good uoa numbers and doesn't cost alot. Found everywhere.)

German made Castrol: 0w-30 (very pricey super hard to find the "green stuff", but really awesome uoa numbers. Autozone used to carry it, but only has the amber color stuff now.)

I bought the Castrol 0w-30 because it's suppose to protect the engine during cold startup really well.

 

motul 5w30

 

Crisco

 

thanks for all yall input specially this one....

 

If you do rev up alot, then I recommend the synthetic oil. Otherwise, any regular oil will do. I dont like pennzoil, but you can try valvoline or castrol.

Castrol GT (semi synthetic) will be the best bet. Cheap and good oil.

The only question I had left is if Original Nissan filter or other brand? (Like purple royal)

 

i guess im gonna try the castrol 0w-30 german made....see how it goes peace!!!!

 

The truth is that pretty much every engine oil does the same thing and your engine could really care less.Everyone globs on to the hype which is promoted by the oil companies to sell their product because they also know this.
don't get caught up in it too seriously.In saying that I love sellling super super oil everyday cause the profit is better.As for filters,yes be carefull.Too much off shore knock off filters around.Actually an OEM filter is as good as they get.Every one says Frams suck but they still sell 20 million a year

 

eneos oil5w30 full synthetic is good, i use it

 

got me some castrol full synt 0w-30 from pepboyz made in germany haha 6.99each...lets try these badboys..and a pricey a** mobil 1 oil filter 10.99...

 

0w30? oh man

 

Getting pretty close to Crisco,I'd say

 

I've used Mobil 1 5W-30 for 36k miles, no issues what so ever.

 

i live in cali, and its getting warm here soon..0w is too thin i might just return these and get mobil 1 5w-30...

 

+1 Thats what I use in every car Ive owned.

 

I bought some GC for my first oil change. Let me know what you think if you happen to put it in?

 

I ended up using m1 n I think I hear her saying "thank u your so sweet..." haha . I notice the smoothness of the engine n better responsiveness...so Im gna b sticking with M1 4 a while....
