Which Engine Oil

[TYREDNGRUMPEE]

just 10w 40 semi synthetic will do the job

 

And if you are in the UK, the most economical / quality product would be the Halfords SEMI synthetic option, simply because it comes in at around £30 or less and there's 5 litres of it, rather than the silly 4 litre measures most others offer.

 

Bear in mind, that you'll be wanting a bit spare for top ups between changes.

Typically, I can end up using more than 4 litres on a oil + filter change anyway and would be fooked if I bought my oil in 4 litre measures.

 

I've used Halfords Motorcycle semi-synthetic 10W40 for six years without issues.
