Stevejames Posted October 31, 2022 Share Posted October 31, 2022 What engine oil should I use? Mk4 Spitfire engine rebuilt but never started or filled with oil. Is it still Duckhams 20/50? Cheers, Steve Quote Link to comment Share on other sites More sharing options...

Clive Posted October 31, 2022 Share Posted October 31, 2022 Possibly a running in oil would be wise if the bores have been honed an dnew rings (or a rebore) Otherwise almost any decent 20/50 is fine for most people. A better class of oil is a good idea if driven hard (ie thrashed, the RBRR or 10CR type of thing) Quote Link to comment Share on other sites More sharing options...
RobPearce Posted October 31, 2022 Share Posted October 31, 2022 I generally use Morris Goldenfilm for engines with good oil pressure, or Penrite 20/60 for those that need a bit of help. I always used to use Duckhams but it's not so easy to find these days so I buy online, and the Morris seems good. Quote Link to comment Share on other sites More sharing options...
PeteStupps Posted October 31, 2022 Share Posted October 31, 2022 Whatever you go for, Opie Oils have regular 15% discount offers so I signed up for the emails and buy whenever it's cheap! Quote Link to comment Share on other sites More sharing options...

I got 20% yesterday. Very nice, as I bought 5L each of Dynax S50 and UB, plus 20L of millers 20-60. Really sweetened the deal 1 Quote Link to comment Share on other sites More sharing options...

standardthread Posted October 31, 2022 Share Posted October 31, 2022 (edited) When I first started driving and maintaining Triumphs years ago I used to use Duckhams. When I needed some more I couldn't get it so I switched to Castrol GTX. On doing so someone told me to stick to one or the other because they aren't (weren't) compatible/mixable, one being mineral based the other vegetable (or similar) based? From that point I have stuck to GTX from Opie. Edited October 31, 2022 by standardthread Quote Link to comment Share on other sites More sharing options...

Much appreciated, cheers, Steve I use Halfords classic 20/50 it’s always given me confidence and looks and smells just like the proper greenish coloured Duckhams 20/50 Quote Link to comment Share on other sites More sharing options...

A better class of oil is a good idea if driven hard (ie thrashed, the RBRR or 10CR type of thing) Clive is spot on with this advice, even more critical for a 1500, but still very relevant to a 1300. "bog standard" 20w50 is fine for general usage to even moderate mileage / performance. BUT if you plan some hardcore motoring it's well worth investing in a premium oil, Penrite, Valvoline or Millers performance oils for example. 1 1 Quote Link to comment Share on other sites More sharing options...
Tim Bancroft Posted October 31, 2022 Share Posted October 31, 2022 Valvoline VR1 or Classic Oils Heritage 20w/50. Quote Link to comment Share on other sites More sharing options...
TRTOM2498 Posted November 1, 2022 Share Posted November 1, 2022 Penrite 20/60 will be perfectly adequate here, & holds its viscosity very well. Quote Link to comment Share on other sites More sharing options...
