as above what do you lot think . ive been using castrol rs 10w 60w but heard on here its not the best to use .what do you lot recomend

 

mobil 1 15w50 or castrol 10w60 is what i used!

 

do you know what harvey reccomends . i havent got my car back yet havent heard a thing this week. he must be bizzy . he is doing it in his spare time tho.

 

Is this for running in?

If so all the oils mentioned are no good, you want a crap mineral oil

 

Yep I've heard this again and again, but can't for the life of me remember why. Anyway, I'm off to get some popcorn

 

its for after ive run it in just getting ready for when its done what do you use

 

It works too well, and the rings dont have enough friction to bed in on the bores.

 

any of those above i would be happy with personally, i wouldnt ever go down to a 0/30 or 5/40 like some people do though, its my belief that this is too thin for the bearings on a YB

having never really used a YB in any real anger on trackdays or anything though whilst comparing different oils, my advice is only my opinion and not the result of experimentation, so i would suggest asking Harvey, especially as he is the one who has built it.

or PM oilman and ask him to contribute to this topic??

 

yeah,those oils i said were for when its up and running!

 

ok thanks guys

 

think harvey reccomends shell helix?

not too sure

 

mobile1 15w50, matt lewis sells it dead cheap on here as well mate

 

Chip ,
I used castrol RS 10/60 at brands a few weeks ago in my RS 500 , after race 2 i noticed a real drop off in oil pressure that i never got with a Motul or Silkolene , i wont be using the Castrol again .

 

Run in on a 10w-40 semi (it will be petroleum based) and then change to Silkolene PRO S 10w-50, PRO R 15w-50 or Motul 300V 15w-50

Cheers
Simon
