Mixing oils?

[RObErT_RaTh]

Hey guys, I normally use Castrol Magnatec 10W40 but when my car got a service today they didn't put magnatec back in, they went with Martini GP oil. I just bought a brand new bottle of magnatec and I don't want to waste it, will these go together or should I just buy the new oil from now on? Cheers

All depends was it shaken or stirred?
Because james bond prefers his martini's shaken

mixing the oils shouldn't be a problem

you wont do any harm in mixing oils.

Hi,

I assume by "serviced" you mean it got the old oil drained, new oil filter and the Martini oil put in?

If so, then just leave it until the next service and tell the dudes you want Magnatec put in. You may have to supply the Magnatec to make sure they use it.

In the interim, why are you adding oil? Does your car use/burn oil to such an extent that it needs topping up between services? Personally, I wouldn't mix the oils - but that's 'cos I'm a fussy old fuddy-duddy.

Technically, mixing the oil isn't going to do any damage or anything like that. It will still work and lubricate your engine. I don't know if the small addition of Magnatec would be able to make use of its "magnetic" abilities as it will be quite diluted (with all the Martini oil).

I'm also assuming here that the oils are similarly based... that is, both are mineral or synthetic. If mixing oil it is best to stay with the the same type. Also, if you demand a lot from your engine - race, drags etc, then I'd not mix the oils.

Correct

I said it was running magnatec when it went in under the assumption that's what they'd use but yeh

Yes it does use a bit of the old oil and needs topping up every now and then

Excellent

They are both mineral based as far as I know. I don't race, I don't drag, just a bit of the old spirited driving every now and again.

Thanks for your help mate

magnatec = synthetic??

[Aust162]

[RObErT_RaTh]

Hi,

Isn't Magnatec both - that is; it's partially synthetic?

What is Martini GP oil? I did a web search and didn't get a good hit to give me nore info.

Its got some synthetic ester thing in it. Thats the part that makes it "stick" to the engine parts, hence it's name. But its mostly a mineral oil, but "technically" a semi syn.
