Oil

[Forumadmin]

I can recommend Rock Oil's Strata 20w-50. I have used it for years and found it fine for our engines.

My local depot supplies me with 25l drums at around £50. This makes a refill oil change for the Javelin about £10, which is pretty reasonable. Apparently, the Harley Davidson Club use this oil as their preferred lubricant.

The ratings of this oil mean that it doesn't result in excessive camshaft lobe wear, which I believe can result from ultra modern oil formulations.

All the best,

David

Paul, it depends a bit on what is in there right now. If you are using a more modern multigrade e.g 20w50 then you should use that as the detergent additives may not mix well with older type oils.
I prefer straight mineral oils and personally tend to use Miller's 30 or 40 depending on how hot the weather is.
You may find Morris' from Shrewsbury easier to find in your area. I would suggest straight 30.

This thread is also good to understand which oil is best for your Jowett and the way you drive it. It really depends how old or modified your engine is and if you use it for short or long journeys.
