Go on - you all know you want to compare and discuss oils!

If that Halford's"Classic" brand is green in colour (reminiscent of the old, original Duckham's 20W/50), I used it in the newly professionally rebuilt, tuned up Reliant 850 engine in my Liege Sports car when I took it on a touring rally to Spain and France.

After returning home 3,000 miles later the engine was rattling and I needed to change the big end shells - again! Say no more, save to say I'll never use it in any of my vehicles again.

You'll get a completely different result in a Perkins 4108.

I must admit to having good luck with Comma X/flow W20/50 in both asbo 30 and the Harley

Think that's the Perkins we used to use

I don't think so, Dai, the 4.108 is only a little under 2 litres.

That sounds right 50ish flat out 50mpg

Did they make a 4.308 that seems to ring a bell it was back in the early 80s so I could well be wrong but I am sure it was only about 2litre

Now I'm feeling old again Dai

The Perkins 4236 was a common one to use in Range Rovers. The 4 denotes the number of cylinders, and the 236 the capacity in cubic inches, which works out at 3,863cc.
Detroit Diesels used similar. An 8V71 engine indicated V8 configuration, and 71 cubic inches per cylinder.

Now there's a bit of useless information pre breakfast.

International Harvester also used their engine sizes in cubic inches to identify them, with letters in front to denote where they were from and whether petrol or diesel - a BD 281 for example, was a British built diesel of approx 4.5 litres [281 CI] in size, while a DTI 817 was an American made [no prefix letter for country of origin] diesel turbo intercooled job, far too big for a Range Rover!

Sorry Paul

Didn't mean to hijack your thread but it's more interesting than oil talk

To be honest I have always found assembly lube and running in to be just as important as the oil you run in the engine

Paul B.W. I haven't forgotten about the Amal pilot jets and velocity stacks I will drop them over sometime

Sure the Perkins we put in where about 2 litre

I also remember putting a sherpa diesel in a marina using a MGB bellhousing

Totally of topic Dai
