Mobil 1 0w40 oil help?! It doesn’t say 503.01 on the back? Do I still put it in?

So I’ve done some reading on the forum and it advised me to get this;

I’ve just picked it up and realised it doesn’t say “503.01” on the back? I don’t know what it means but judging by the post I was reading it’s essential to be 503.01. So the question is, do I use it or not???

Here’s the link to the thread on this forum that I’ve been reading;

504.00 superceded 503.01 .

504.00 superceded 503.01 .

So it’s okay to use this oil then?

£70 very expensive Oils have improved and been updated since the handbooks for the 8LS3 were printed. The thread you have copied is an old 2005 one. This one may be more helpful - see recommendation 29/Oct/2009

What engine is it going in. I wouldn't put 0w-40 oil in a 1.8T especially if it's mapped. It's too thin.

40 grade isn't thin .

I've just been buying the Halfords own oil on offer I think it is £20 for 5 litres for the Audi/VW and less for Ford/Merc

So what are we thinking then guys? Take this back and go quantum 5w30? The car is at 173k and is going for a dyno remap at badger5 at some point.

Mobil say it "meets requirements" of 503.1

If I owned your car, would I worry about using this oil (on a non long life basis)? - NO

Any fully synthetic 5w-30 or 5w-40 will be absolutely fine in your car, changed every 8000miles or thereabouts.

There is far too much ******** being spoke about oil.

As long as its changed regularly, engines are not too fussy about what you put in them.

tend to agree Seen plenty of engines ruined by terrible oil (lack of) servicing but never one ruined by not dotting the finer "is" and "ts" on oil small-print selection.

0w40 is fine. It’ll actually perform better at cold start in cold weather
