Fish Posted May 9, 2009 Share Posted May 9, 2009 Hi AllCan anyone recomend the right tpye of oil I should be using in my Stag. It has a 3 litre Triumph engine and is currently running Castrol RS 10W40 but this feels a bit too thin. Would I be better off with a 15W40, a 20W40 or something else and is there a particular brand that would be best suited please?All the best.Andy ??)

steaming Posted May 9, 2009 Share Posted May 9, 2009 Handbook says Castrol GTX, but that is GTX of yesteryear.I use Halfrauds Classic Car oil, which i think is 20w40. Anyway engine seems to run ok and looks the right viscocity. Link to comment Share on other sites More sharing options...
lordleonusa Posted May 10, 2009 Share Posted May 10, 2009 See this dissertation and find oils with enough ZDDP, or say goodbye to your engine.http://www.lnengineering.com/oil.htmlL Link to comment Share on other sites More sharing options...
CotswoldClassicCar Posted May 10, 2009 Share Posted May 10, 2009 Millers Classic 20w50. Anything too thin will p1ss itself out of all the wrong places. Halfords classic 20/50 is OK too, and Duckhams still produce a 20/50 so far as I know. 8) Our Stag gets fed with Millers 20/50 and seems to thrive on it. I tend to use Millers in our other machines too. Link to comment Share on other sites More sharing options...
GT6 John Posted May 10, 2009 Share Posted May 10, 2009 If you're going to buy Halfords Classic 20/50 in the posh metal container and why not, there's nothing wrong with it, then consider buying Comma 20/50 in the cheap plastic bottle at up to half the price. It's the same stuff! Link to comment Share on other sites More sharing options...

StagNL Posted May 10, 2009 Share Posted May 10, 2009 Personally I use Valvoline Turbo V - 15W40. The stuff is usually on special at my local automotive supplier.It is a 100% dino oil. My employer puts a semi synthetic oil in his Stag but Iam unsure of the make and viscosity value.Last I heard is it is better to use 100% dino oil in the TV8.Julian Link to comment Share on other sites More sharing options...

I had so many problems with a previous Stag that I simply decided that the present one should have decent stuff to work with: cheaper in the long run and all that! 8) Link to comment Share on other sites More sharing options...
FloydP Posted May 12, 2009 Share Posted May 12, 2009 Colin, the best price for Millers classic sport I've found locally is £26 from MJP eastern autos near Brentwood, not exactly local to you but at least it's in Essex.Floyd. Link to comment Share on other sites More sharing options...

Doug Paterson Posted May 13, 2009 Share Posted May 13, 2009 Another worth considering is Valvoline Racing 20W50. Not the cheapest but I know a chap who gets it in bulk (i.e. 3 or 4 at a time) for about £24 a can.Plus I got my last one for free in return for technical help given Link to comment Share on other sites More sharing options...

I thought I was being all original, too! I was watching Black Adder for the umpteenth time, and the idea for the avatar came from that. Someone else was bound to have had the same idea, it was inevitable!I change mine every few months anyway. Once I find something else I like it'll change!
