Which Oil Question, Again?

[tvr5000]

Hi,

It's oil change time and I can't remember what went in last time. I've looked back through the Oil topics but it seems to be a minefield.
I was advised against fully synthetic by Speed Six in Henley, so that rules out Mobil 1.
Whats the best out there for normal TVR driving. Considering Magnatec.The engines still tight so there's no issues with burning too much oil.
Advice much appreciated.

I ran castrol magnitech 10-40 semi for 3 years and gave great oil pressure all the time.

You will now get 15 different answers, but

I think something reasonably thick minimum 10w50 with plenty of zinc to help the cam. I dont understand why fully synthetic should be a problem as if carefully chosen it performs better than mineral.

Personally I have Motul 300v 15W50, but I appreciate it is expensive.

Im useing valvoline Vr1 mineral 20w50 and runs a treat..I may move on to Millers 20w60 css semi synthetic because the engine as done around 5000 miles..Don`t think im going to bother with fully synthetic !

1+ on 10/60

Best pressure and temp ive had so far

I use Mobil 1 Motorsport 15/50. Buy through eBay so it doesn't cost too much (£68 for 10 litres was the last auction I won)

The only case against synthetic as far as I can tell is how much it costs against the fact that the Rover V8 is quite happy on mineral oil.

Can of worms opened!!

I was running fully synth 20/50 i think and seemed to suffer high oil use with no obviously apparent reason. Engine was only rebuilt a few thousand ago so have gone back to mineral of same viscosity to try and reseat things - oil use seems to have dropped dramatically!

Wierd and of no use to anyone I realise

Valvoline VR1 Seemed to use a lot of Magnatec for some reason, better now on VR1.
