Just checking wki here and halfauds and opie oils and my own paperwork and they all say to use 5w/30 engine oil.
Noticed in my garage part can of 10/40 which I used last year after taking notice of the Euro Parts web site .
Not had any issues this past year so hoping using the 10/40 has not had any affect long term??

This may help explain....
Jim that's a really good explanation to those that didn't know.. I always used to remember it as if reading from left to right - "you get in the car and start the cold engine which then becomes hot" - but remembering W for 'winter' is just as simple if not even more intuitive.
I've always favoured fully synthetic oil as its slippery stuff and tends to stay in grade well - but is there any reason you should NOT use fully synthetic in the Jimny engine?
IF IT AINT BROKE, KEEP FIXING IT UNTIL IT IS

Price is the only reason. It is over-spec, but that certainly won't cause any problems. Equally there are no advantages to using it either. I've never heard of anyone having any issues with the oily bits of the engine.

The reason I started using synthetic was because my cousin rallied several cars and managed to continue for an amazing distance with a split sump. He said he'd noticed the drop in oil pressure but believed it was a broken gauge. Only when he saw the oil temp go off the scale some time later did he realise the situation, and stopped. There was damage to the engine but it was in his words, it was minimal, and I was very impressed by this.
I've heard that older cars (classics particularly) can tend to leak synthetic oil - as it's thinner presumably.. I did use it in my '79 Midget back in the late 80s without any noticeable leaks at all, but I now prefer to use the classic oils in that car.

I know that to be true as it's well known and understood in the vintage car world,
