Good evening,
I've been researching the forums and trying to understand engine oils. I'm going to have a go at servicing my car soon. It's due in 5000 miles and I'm afraid of the dealer quote....

What's the best oil to use?

I don't understand the various grades or groups and whether or not an oil is BMW spec. Can anyone help a noob?

Normally I'd just input the reg into eurocarparts and see what it throws up but I want to be a bit more careful this time.

I have a 2015 320 efficient dynamics with 71k.

Thanks (again)!!

James

Phone up Opie oils.co.uk. as an engineer, I fully recommend Fuchs fully synthetic oil, and either 5w30 or 5w40 grade. Opie will be able to advise you on your choice and how much for fill, but I would buy in bulk for 3 or 4 changes. This will probably work out to be by far the cheapest option.
I use Fuchs xtl 5w40 fully synthetic on the 435d.

Fuchs gt1 xtl 5w40 was the same oil I used on my 320d with n47 engine.

Currently on fuchs gt1 pro c3 5w30 on my 335d but will probably change to the slightly thicker oil after 100k miles.

Thanks for the advice both.

I'm went with 6l of millers 5w30 LL04 spec oil. You can check your manual if you're concerned.

I do a lot of town milage so I change my oil every 9K

Oil & BMW filter £70. task 40min with a cup of tea.

You need an oil that meets the BMW LL04 spec, either 0w-30 or 5w-30 are the norm and there are even some 5w-40 out there as well.

All of these are either BMW LL04 approved or happily meet the requirements of https://www.opieoils.co.uk/c-686-bmw...ngine-oil.aspx
