[jonny car roll]

i've recently purchased a 94 chim and can't wipe the smile of my face! also looking forward to the run down to lemans with fellow petrolheads and my bro. anyway i need to make sure the old girl is on top form....the car that is and some advice on what type of engine oil. aware mobil 1 but what viscosity? plus where can i get a filter from and does any recommend anything else i should do? apart from have a spare car trailered!

[MADMAX2]

I use MOBIL1 15/50 i know its not cheap and there are many as good as alternatives out there which are cheaper but it aint no fun if your wallet doesnt take a pounding .....

Another vote for Mobil 1 Motorsport, they sell it at Halfrauds.

[DavidLScott]

And me - as recommended by Fernhursts.

Mobil1... me too

Sorry to break the Mobil run, but I use Silkolene Pro S 10w50. Oil filter was just a Halfords HOF249

I've used Magnatec 10w40 for oh years now. Engine loves it. Dont put standard Mobil 1 in, its too thin. I know some people swer by the thicker Mobil1 motorsport stuff but its damned expensive.

Wise wordsyour Magnatec is more oil than this engine needs anyway,although i do like both the 15/50 Mobil 1 and know the silkolene is good stuff,i was using vauxhall fully syn for a while 5/40 and had no problems even oil consumption was good,but they have replaced the 5/40 for 5/30 and that stuff just wont doso am on the Mobil 1 15/50 changed today strangly enough with a new sump gasket and oil strainer gasket and blue thread lock(good insurance)thankfully no nasties in the sump(my 1st inspection);)although cam as slight pitting on lobes so thats a job for the winter(not milder but wilder)

cheers for the advice,on the basis of popular demand it looks like the mobil 1. interesting you mention a cam upgrade as i started another thread on poss mods for my 4l chim what cam you thinking of and do you recommend other work to do at same time?

Magnatech
BTW £9 per litre compared with mobil @ £15 per litre plus filter that's £100 and that's if your doing it yourself.
Bit of a shock init.

If you're going to cut costs then I don't think oil is the right thing for it. Not that there's anything wrong with Magnatech, just Mobil has such a good reputation.

I've been using Shell Helix Ultra 5W-40. Anyone else used this?

[Red V8]

Mobil 1 whilst expensive is bloody good... you need to take good care of your mechanical heart, if you're going to spend money anywhere then spend it here... and you only fill up your engine once a year... I just think of the cost as an extra tank or two of fuel, most of us don't hesitate to shell out £50 or £60 quid a go for fuel...

[bigdods]

I had a bad experience with standard Mobil 1 when I first bought the chim. Made the engine rattle and misbehave. That was when I changed to magnatech and never looked back :-). I could change to the motorsport mobil 1 but to be honest Ive used magnatech for 3 years now and am happy with it so see no reason to change.

I had no problems with 5/40 fully syn and seeing as your using a good brand fully syn then i think its all good.

Yup - This is what Leven put in my car

[mb450]

Motul 300V 5w/40 on Opie Oil's recommendation - seems very happy with it

[That Daddy]

Wait for it someone will post shortly that 20/50 is the best motor oil to use in the RV8 because its so old

[dwgriffith]

Yep! Valvolene Racing 20:50.

Why do so many owners still vote for Mobil 1? The reason TVR promoted its use had much more to do with the lucrative business arrangement than any performance benefit, TVR got their supply for free so long as they put an 'Only Use Mobil 1' plate under the bonnet. Many people who currently race Rover V8 derivatives use Castrol Edge 10W 60.
