Thanks guys, i was wondering haha...well so 10w-40 which im running now would be a good one seeing how im in Texas lol....im gonna go with amsoil =) 10w-40 fully synthetic

 

Just make sure it is JASO-MA certified for use with wet clutches.

 

will do =) thnx

 

i run castrol 0w30 European formula in my Supra, and am planning to run it in my F1. this is a link to a page that explains it all, and that's why i use what i use. Motor Oil

 

Thanks for the info link bro, i do like what i see but im pretty set on amsoil, thanks for the idea though

 

suit yourself, but 1 other thing you should take into consideration, is price and availability. the castrol is less expensive, and you can get it at most autozones. the castrol will do virtually what the amsoil will do.

 

good point....that is true...i'll think about it =)

I dont know about 0w, doesnt sound good to me. You ever leave a girlfriend for somebody "better," and realize, the first one was just fine? Well, if you leave Mobil 1 10w40 for anything else, you wouldnt gain anything except the fact that you spent more money for nothing. Im a die hard Mobil 1 user.

 

if you were to read dr. haas's studies, you would see that even 0w30 does not have the cold flow rate for full startup protection. however, it is far closer to the ideal flow rate, than 5, or certainly 10 weight cold oil. as stated, i run this in my 92 toyota Supra, which calls for 10w30 as standard all weather oil, and 5w, in colder climes. it would have been far too an enormous task to put up links to all the info i read before choosing 0w30, but at any rate, i am using it in an engine the pushes 14 psi boost, and it is running perfect, and has the best startup flow protection available. the only thing i'm not sure about, is clutch performance, but i never ran jaso certified in my 86 vfr750, and never had any clutch issues. i'm taking into account the improvements in oil since then, but i will still give it a try, as soon as i weld the damn frame crack. i'll update on clutch performance when i do.
