Which oil ??

[Ifan Evans]

Hi all,, I was wondering which oil you put in your z3? What's the difference between 5w30 and 5w40 ? I've a 2.0 2000 model. Anyone used that Home Bargains oil, seems like a bargain ...

Home Bargains oil I think is only semi synthetic 10/40? You'll need fully synth, I use 5w40 Triple QX from Euro car parts they always have an offer on oil and filters I think it's 35/40% at the moment, I use a Mann oil filter comes with a sump plug washer and filter housing seal, I would also replace the two small O rings on the base of the filter housing, I do them every other year they are a dealer part.

I'd look at doing the gearbox and diff oil as well as its not on the service schedule BMW think it should last the life of the car!

I changed Engine oil,gearbox oil and diff oil in the last few month, got them delivered from Opie oil,top quality oils at reasonable prices,oil was Shell Helix Ultra 5w-40
The oil filter came from BMW and I think all washers came it , I had included the washers from Opie,so had spares
It has really improved the gear change,
I consider the term "sealed for life" means until the part packs up because the oil is worn out.

It's this, I know many z3s use oil so not much point in buying expensive oil

 

[Taz Horton]

It's up to you but cheap oil usually means just that . Oil is made up of addetives which are expensive and the company put them in to bring it into specification so a cheap oil will in effect run out of specification much quicker than a premium oil , if that makes sense . It's the life blood of your z ,, I personally don't drink tesco own brand lager if you catch my drift

But good oil and filters are a lot cheaper than engines.

The difference between 5w-30 and 5w-40 is how thick the oil is at 100°c

Here is a guide for the 1.9, 1.8 & 2.8 but a lot will still apply. Essentially buy good oil, it's not worth scrimping on.

I personally just changed to a Shell Helix Ultra fully synthetic 5w-40 and my 1.9 is running great.

Hope this helps

Does anyone know the recommended oil for the 2ltr ? The owners manual didn't come with the car
