Bob Posted December 5, 2006 Share Posted December 5, 2006 Cheap shit, mate. Oil is THE thing you do NOT want to skimp on with these cars. A cheap oil is bad enough, but a cheap semi-synthetic is bad for any Supra, regardless of age or mileage! Get a fully synthetic, every time - look for Mobil 1 or Silkolene Pro S.

markrzs Posted December 5, 2006 Share Posted December 5, 2006 Silkolene Pro S as the bob says Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted December 5, 2006 Share Posted December 5, 2006 I think you will find that Coma oil is actually produced by one of the major manufacturers, in fact like most of the lesser brands;) and will meet acceptable quality levels, i have used Shell semi synthetic in most of the cars i have owned and never had a reason to change, my Nissan was running over 140BHP over stock on it oh and personally i think if your going to change oil at 3,000-4,000 mls fully synth is a waste of money unless your running 500BHP + Link to comment Share on other sites More sharing options...
hadyn Posted December 5, 2006 Author Share Posted December 5, 2006 Im just thinking with an engine thats got highish miles and hasnt been particularly brilliantly looked after, using cheap oil with very regular changes (2-3k with filter) wont be that bad on stock power?

hadyn Posted December 6, 2006 Author Share Posted December 6, 2006 The comma bottle clearly displays ACCA A3 B3 and API SL CF - as seen below: http://www.commaoil.com/Product%20%20Shots/Oils%20&%20Lubricants/eurolite.gif so surely it must be OK?

Chris and Alana Posted December 6, 2006 Share Posted December 6, 2006 Halfords oils are made by comma and they have the same specs and according to the link, those specs are the ones to stick to as a guide to a good oil. Im no expert at all but why pay £45 on a bottle of oil that has the same specs as the halfords or comma oil at maybe £20 a bottle? Link to comment Share on other sites More sharing options...
hadyn Posted December 6, 2006 Author Share Posted December 6, 2006 Thats what Im thinking Chris:) TBH I'd have gone straight for the Mobil 1 etc with a lesser mileage car, but Im thinking why bother with 100+ k mile car? As long as it meets spec and is changed regularly why shouldnt it do the job? Link to comment Share on other sites More sharing options...
Chris and Alana Posted December 7, 2006 Share Posted December 7, 2006 Well my soop has 47 thousand miles on the clock and I was just going to get a well known brand like castrol etc. However after reading threads I found that a 5w40 fully synthetic is what is recomended and there seems to be a lack of that grade apart from the Halfords oil. I didnt seem to sure if I should use halfords own brand oil but when you look at the specs it seems spot on and its not a synthetic blend either. (as far as I know) Apart from that I was thinking Castrol edge 0w40 but I read on here 0w is too thin and can leek past oil seels etc. Could someone in the know please solve this and explain a reason why we shouldnt buy the cheaper halfords oil at half the price that meets the required specs for a 'good oil' and also does 0w40 do any harm or would you stay clear?

geoffvalenti Posted December 7, 2006 Share Posted December 7, 2006 I'm sure that "oilman" will be along soon to wax lyrically about, and extol the virtues of, the expensive oils that he sells. Undoubtedly if you've got a new car that you intend to keep for a long time, or one that has been modified to produce a lot more power than standard, using the best oil available, and changing it regularly is to be recommended. However if your car is of unknown origin, fairly stock power levels (no more than BPU) and/or high(er) mileage, then starting a regime of using eye wateringly priced, designer oil, is literally throwing your money away down the drain (at the oil recycling centre ) Personally I'd recommend using a brand name fully (hydracracked) or semi synthetic and changing it, and the filter every 3000 miles Obviously if you're doing trackdays, or live and die at the Pod etc. then you should use the more expensive stuff, but for normal use to and from Tescos and the like, oil meant for Formula 1 cars isn't really required As for viscosity, Toyota in their wisdom recommend a 10w30 weight oil, so something around that is what you should be aiming at (10w40, 5w40 etc) Personally I wouldn't advise the piss thin 0w grade variants, but each to their own Link to comment Share on other sites More sharing options...
supRo Posted December 7, 2006 Share Posted December 7, 2006 I use 10/40 semi synthetic usually shell helix sometimes halfords own brand and the stuff that Phoenix Garage in Watford use. I have done about 35 thousand miles of quite hard driving (BPU). I change the oil about every 3.5-4 thousand miles with a new filter. My car has done about 117,000 miles in total. My car is still going strong, nothings leaked or popped and still has stock twin turbos. I don't even have the blue start up smoke. I personally feel it's not worth getting the expensive oil if you do oil changes every 3-4 thousand miles. Link to comment Share on other sites More sharing options...
