i know there are diff opinions, but what are the ones that you guys use?

If you can get it! Fujita Engineering rotary engine oil "FEED"

Ok. Let me ask you this.



How did you come to conclusion that FEED oil is the "best"? Can you explain exactly HOW and WHY you think it is the "best"? I'd like a solid answer. I don't want a cheap reply "because FEED uses/sells it so it must be good".



And more importantly, DO YOU USE IT? (after all, twinturbodork also asked about which oils you use)

Never mind.



Turns out, you don't have a rotary engine powered vehicle.

So WHY are you telling him that it is the best when you have not tried/used the product???

FEED uses it...must be good! https://www.nopistons.com/forums/pub...1047683664.gif



Great company makes great things...there was a post about this and i think JT-imports explained why its a very good oil and better than regular oils.

JT used RE oil, said nothing about how "good" feed oil is.

nah there was another post about it where is said more detailed stuff...

like how it is most likley just another oil put in a feed can.

Im in love with SPEEDMASTER, but REDLINE seems pretty good too.



Speedmaster--Is only available in Japan is far as I know, but has many grades, it might also be a branch off of some other company, but since its not that badly priced, it might not.



Yeah the RE-Amemiya oil I used made the engine feel smooth as a babys butt, but I think it hurt the engine some. I dont have any expericence with FEED oil, except for the MIXTURE oil. I would love to get it to the US, or at least bring some FREE to the US, but I dont have that type of abilities for shipping as of yet, unless I want it to take 10-14 days on a ship.

imho twinturbodork

proper weight selection during seasons and frequency of oil change are factors to be considered..

as far as which best.. youll find most are just claims...

stick to recommended SAE and youll be fine..

in the issue of dino versus synthetic... its an ongoing debate..
