Oil for Griffith

[Corky]

Grateful for some advice please, I have been offered some discounted Castrol TWS 10W-60 oil, I normally use Mobil One, would using TWS be OK, 65k on engine, new cam at 55k.

FWIW this is what the Dutch TVR importers use. Opieoilman seems to think it's too thick (specifically the -W60 part, contrary to popular belief the part before the W only applies to how well the stuff flows when cold and has nowt to do with oil pressure or consumption in a warm engine, apparently) but all the better known fully synthetic Motorsport oils on sale here (Millers, Shell Helix Ultra Racing and Catrol Motorsport TWS) come with this viscosity index.

I'm running Shell Helix Ultra Racing 10W60 here - not to be contrary, but after fruitless calling around I couldn't find a place that would do an oil change with one of Opie's favoured blends so it was either 10W60 Castrol at the TVR importers' or 10W60 Helix Ultra racing at Beek Auto Racing (who have always taken care of my Sweedspeed-engined Saab); the former were booked solid for a month or so, so the latter it was... (I'd normally change the oil myself but I was wary of the 'zero oil pressure after letting oil flow out of the oil pump' RV8 snatch, especially given the recent incurred cost on this car/engine...

Sometimes you have to be pragmatic.
