My Oil choice.

[Cubes]

Hi ppls,

Now the motor is well and truly run in I am going to go for the Motul 8100 X-CESS 5W-40. Its a decent synthetic oil that is PAO, i.e not a half arsed synthetic.

The next step up from PAO is the ester based oils which are big $$.

Close to $100 for around 5ltrs.

The Motul 8100 X-CESS 5W-40 is $59.95 for 5ltrs which is fairly decent.

It should be interesting how the 5w-40 goes, there is a bloke at Autobarn that runs it in his RB26DETT. Its fine and holds oil pressure in heavy traffic (unlike mobil 1).

Let me know of any experiences with this oil.

Why bother about $40 with such a nice engine?

I blend the 300v to get 7.5W-35 personally. Idle oil pressure dramas have dissappeared since I started doing this.

[Abo Bob]

Sorry. I know that doesn't answer your question. I'll butt out now.

I'm not going to play around mixing oils.

$40 adds up over a 5,000km change interval.

I'll see how it goes, if the oil analysis comes back nice I'll stick with the oil and possible extend the drain intervals.

I've seen a few analysis reports with the Motul gear and it is a pretty damn good oil.

If the report contains a little too much bearing wear I'll jump up to the 300v.

I do quite a lot of kays ~30,000km's per year.

It all adds up. Especially Studying full time at Uni and trying to support my continual list of mods habbit.

Goto www.Motul.com and have a read about 300v

If I was going to go for the 300v I would prefer to go the Amsoil.

Ive run Motul 8100 for the last 3 or more changes.

Found the response a little better than Mobil 1, but i have no idea about wear on bearings etc.

I'm thinking of changing to Castrol Formula R (a lot thicker tho) to see how it goes.
