Hi, as above, the details here https://www.brickwerks.co.uk/jx-engine-data/ seem to suggest that it is 15W/40 (CD).  Does that sound correct?


Thanks

A high performance 15W/40 Mineral Oil is what is generally recommended for a JX engine.

FYI - the correct oil grade is actually dependent on the typical ambient temperature that the vehicle operates in. There’s a handy chart in the VW owners manual that shows which grade and specification to use. A 15W/40 oil is suitable for a UK-type climate, but in colder climates it might be more appropriate to use a 10W/40, whereas hotter locations might require 20W/50.

E D I T: There's a whole page on engine oil here in the 8090 Wiki.

Thanks for the reply.

Similar, can anyone suggest the right coolant to use please?  Should mention that he coolant in there at the moment is a blue colour.

Thanks

Pretty sure it’s 15/40 semi synthetic, but I’ll double check

Thanks.

The coolant in there at the moment is a blue colour.  Anyone know if this would be ok https://www.eurocarparts.com/p/triple-q ... -523770502   It's towards the min reading on the tank and I'm away tomorrow, so I need to get something at ECP or Halfords.
