Might have bought the wrong oil ! 00 - 40

[Jon_Bentley]

picked this up at costco a week or so ago, thinking mine would need topping up (which it still doesnt ? even checked the dipstick on the level and still at the full mark) but now not sure if its the correct oil anyway

so question, is it and if not can it be used for topping up ( oh and its mobile 1 fully syn )

For topping up there shouldn't be any probs at all Jon, as long as you already have fully synth in which I would bet my mortgage you do

The 00 may be a touch thin if you filled up from scratch ... but then again, with this "scorching" summer weather we're having, maybe not!

0W 40 Mobil 1 is what Porsche say should go in the 996 TT, not sure about N/A 996's, but should be fine for topping up.

Was about to buy some Mobil 1 the other day to top up the RS.
Choice was 0 -40 or 10- 50. Both fully synthetic.

What is the difference?

My 996 is on 115K miles now and at my last service (at an indie) was advised to move from 00/40 to 10/40 as its 'thicker' and will keep my oil pressure that little bit higher (has dropped to 1.2 bar when hot at idle using 00/40) as my engine is 'nice and loose' (a rather polite way of saying a high miler!!!!)

the 0-40 will by ever so slightly thinner, but they both have the same cold/hot change in viscosity, i.e 40 points. Ok for a modern tight engine, but on the older engines you would be better off with something like a 15-50.

Do a Google on oil viscosity ... it's another world :geek:
