Engine oil
Turbo Mini Forums

Just wondered what engine oil you guys use in your turbo engines? Im currently running on Valvoline 15/50 turbo oil with a STP and an engine stop leak. Replaced the oil with that conbination a couple of months ago but the engine is starting to sound abit noisy, so was thinking about draining it out and filling with Duckhams green 20/50. Do you think this will be ok for the turbo or will get to hot and burn?

cheers

Castrol synthetic 5W50.
Keith Calver published a recommendation on his site to use synthetic Torco 0W20! He said he ran this in street and race cars and saw lower oil temperatures and great wear performance on teardown of the race engines and transmissions.
I'm going to Redline 5W40 with the next change - supposedly the best high temperature performance.
To muddy the waters further though, my engine builder friend swears by Chevron synthetic now.
At any rate - synthetic all the way. Also to my thinking, you need a 5W or 0W if possible for winter driving - get that oil flowing at low temperature.
If I get brave I'll try Calver's thin synthetic recommendation.

Really!? is that ok for the gearbox? i always thought that synthetic oils were no good for the A-series, especially that thin. My dad swears by green 20/50 in the A-series but i was concerned that it may not be suitable due to the higher oil temperatures with the turbo.

Duchams Q, its the oldest off the shelf API rating, other than the Millers and Penrite range

best bet is millers cvt 20 /50

this time of year go down to a quality 15/50 but i wouldnt go any thiner as the baulk rings wont like it and nor will the layshaft.

valvoline racing 20/50 available from BMG autofactors in Ashstead, Surrey.

Where can i get Millers oil from? never seen it around, or can you ony get it online?

I've been advised to use Valvoline 20/50. Its affordable too

frost sell millers, they were doing free delivery on orders over £80 last month too...

theres a millers site, google it, i cant remember

I used a classic engine oil from halfords, it was in a green metal container and the oils was green IIRC cant rememver the viscosity tho, worked well in my tired engine stopped gear crunching when changing down fast I always like to use slic 50 aswell.

this stuff?

It is very pricey for 20/50 but if its as good as it sounds then i may give it ago.

I was temped to use the green halfords 20/50 have numerous tins of it in the garage, but was unsure if it was ok to use with the turbo.

The only thing I buy from Minisport is the Millers

What is the logic behind this Robert, or is it because you have an easily available source, only asking as I may also be able to obtain this at a reasonable rate myself....if you know what I mean

i have used the valvoline and found it a very good oil, i would use it if i couldnt get cvt.

personaly i think ist the best oil we can put in a turbo lump or any a series for the box.

Cheers for the replys, i have just ordered some of that trans 20/50. Mini sport had it on special offer.

Are people still using rimula? Is it any good still?
