Just saw an ad for this at the bottom of the page while trawling boards

Haven't come across it as a grade, so had a look. Under the additional info tab it says
"Gives excellent grade protection from cold start to high speed motorway driving"

Surely this oil wouldn't be useful in a cold start scenario, being of a higher viscosity, whats it for? says diesels and petrols?? maybe they mean tractors?

Diesel and petrol oils have different qualities so I avoid using any oil that states one size fits all.

20w50 dinosaur oil must have a very limited market.

It's a very thick oil, which many use in "classic" cars. The oil in that link is cheap (and maybe nasty too?).

p.s. I've used Halfords own brand classic mineral oil for the last couple of changes.

Alun

Back in the 70's that was the standard oil used in most cars. Like treacle compared to what's commonplace these days.

Yep, nice and treacly, just the job for Rover V8s and LT95 transmissions both of which are in my 101. The real cheap stuff is fine if it meets the specs, I pay €12 a gallon for it.

It's really meant just for classic petrol engines, you put a modern oil in a basic 60/70s engine and they sound like a bag of nails

Carlube oils are fine, they're made in the UK.


20W50 is usually used in older cars. And in our tractor.
