Oil analysis on GT

[teK--]

Well in a higher mileage engine when there is more wear, the tolerances in all the moving parts is higher, so oil pressure would naturally drop a little. Makes sense to use a slightly thicker oil in that case, but 50W is pretty high for a slighly-modified daily that's only over 100KKms.

I agree with you Tek, a 50W does seem a little excessive for an engine with that amount of klms. I'd also consider using a 5W-something instead so the oil flows that little bit better upon start up.

10w40 is the best to use IMHO - Mind you, not all companies release their top spec oils in this spec (Mobil & Castrol for example) but running a 5w30 or 5w40 should be also very good.

In the Liberty I was running 10w40 RP & found it to be fantastic... I know a lot of the Sydney guys are doing the same & have nothing but good things to say

Since Mitsubishi are annoying with their oil specification, I'm now running Mobil 1 in my EVO. Porsche recommend it & the EVO comes factory filled with it as well... Figured since Porsche use it, Nissan use it in the R35 GTR + Corvette & all high end GM's use it... Pretty sure I can't go wrong

Mobil 1 is a very good oil, it's just quite expensive and I wonder if a big factor is their marketing costs

But yes it is annoying when an oil meets the correct grade but not in the preferred base type or additives package. Australia seems to get a lot of dud oils which are a downgrade of the same ones marketed overseas (even of the same name).

So Jim if price is not a concern what oil should I go for? you still think the Castrol Edge?

So for a car with 110K kilometres, do you (Jim & Q) think that 5W30 or 0W30 (yes I know the 5W or 0W makes no difference once warm ) would be fine?

Yeah that'll do the job; no need to go over the top you should give your extra money to charity

The most expensive oils like Motul 300V or any other ester based oil, is not only the best/overkill but also lasts the least amount of time, so it's less practical if you are using it for regular driving since you have to change it often.

So for a car with 110K kilometres, do you (Jim & Q) think that 5W30 or 0W30 (yes I know the 5W or 0W makes no difference once warm ) would be fine?

5W-30 is readily available (I haven't seen 0W-30 on shelves anywhere), and is your best bet IMHO. If you find you are consuming oil then go up to a 5W-40. The oil that is thinner when cold is going to give you better protection at startup regardless of if the weather is cold or not. 15W-xx is a bit too thick for your engine in Melbourne.

5W-30 or 40 would be ideal. Out of curiosity how often do you change the oil?

I think the last time it was done was before Christmas.

Castrol Edge Sport is a good thing... TMR actually uses this in their race cars & after many meets (Which included Bathurst 12 Hour) the engine still doesn't need any rebuilding & looks as good as new.

Yeah that'll do the job; no need to go over the top you should give your extra money to PHAT GT

FTFY

Mobil 1 ESP is a very good oil

Fixed

So, oil change - should I use 5W30, or should I go 5W40 to be safe?

[Mr Cali]

I used motul turbolite great oil and not over priced. Can find them for $45-$50
I change my oil every 5000k

So, oil change - should I use 5W30, or should I go 5W40 to be safe?

I'd say 5W30, to be safe.
