Title: engine oil Post by: Keithver on 23 November, 2023, 01:04:20 PM I have just rebuilt the engine and am using Castrol running in oil for the 1st 1000km
When I change the oil and filter, should I fill up with running in oil or normal oil. From what I have seen on the forum 20w/50 seems a popular choice On a slightly different topic, I have heard some reports that Castrol oils are a little sludgy and might gum up the works - is there anything in this. If so what should one be using. on page 38 of the owners manual, the suggested oils are 10w-40 and 10w-50 Title: Re: engine oil Post by: LCR1967 on 23 November, 2023, 01:18:41 PM I rebuilt my engine a couple of years ago and used Motul 15W50 from the very start. Change the oil and filter after approx 1500km.

In the 60's and 70's Castrol GTX was the trendy oil to use. I found it sludged up my TR4 badly. Perhaps it was so good it was in fact de-sludging it. I have used semi-synthetic 10-40 for years and it seems good.
