Talking of oil...

[WildfireS3]

What oil does everybody use?

I have Car Lube (the TVR reccomended one) Fully Synthetic 10W 40 in it.

I had a major problem with the oil running low and I didn't know what to put it, so I had it all flushed and then put in the TVR reccomended stuff. The bible says fully synthetic.

Me too. Magnatec 15-40 if i remember correctly. Its been 12 months since i bought some, must get some more while it's still on sale at Halfords

I must confess to using ordinary Castrol GTX at the last oil change. The thicker grade for "ordinary engines". Thats all you would put in a Sierra, and I don't thrash the car. If I start bombing about in it, then I may change to a better grade.

Mobil 1 Motorsport was used very regularly in mine for the past years...i even have the track record stamps for it from the previous owner, looks like it was changed about every 4000 miles which is nice !

Never smokes and has over 100k on the clock

Likewise. Austec were actually quite pleased I hadn't put a synthetic in it !

Is synthetic bad?

[bills1]

Following my engine rebuild I was told to use a mineral/synthetic blend 10/40 either GTX or Valvoline.
These Cologne engines have been in use since the seventies and need the thicker oils.
The main thing is to keep changing your oil either every six months or 3000 miles and of course change the filter.

Mobil 1 Motorsport 15-50.

This ones cropped up before and various things have been said about the oils that are available today and what should and should not be used. The best thing to do is to use a good make of oil to start with and check the grade of oil that the engine should have. Nearly all modern oils are far better now than they were 20 years ago and anyone who says they still use an oil from the dark ages should move on to modern oils.
Most old oils were fine in the summer but difficult to start in the winter so they developed the multigrade to be able to be thin, but not loose viscosity as it warmed up to full temp.
As some have said, the engine was designed in the 80s and this should be taken into account when deciding what to shove into you car.I would recommend that a semi sythetic oil should be used as it has the characteristics of the mineral oil and the steadfastness of the synthetic which will not give way at high temperature. Anyone who is spending £40 for 4 ltrs of oil is over doing it.
If you did put £40 fully synythetic in it you could easy go 6000 before changing but I'd rather put a £15-20 semi in and change every 3000.

What do you think!

Thanks Gadgit, we agree.

I use Valvoline Durablend 10/40 costs £14.99.
As I have already said, this is the type of oil the engine builder recommended and change it every 3000 or 6 months.

I was at Austec yesterday and the subject came up. Paul suggested that standard Mobil1 was too thin for the V6 and V8 but the Mobil 1 Motorsport was ok as it is thicker.

Semi-Synthetic is easily good enough for these motors and the tolerances they are built to
