What oil should i use?

What oil should i use for my 75k service.

MOBIL says 0-40

Are they right? I was thinking more 10-40...

[Veee1.8t]

good question ....i was wondering what oil our cars take?

[william]

as per manual suggests mobil 1 synthetic 0w40sae is recomended

[Kai]

yeah but you cant run 0-40 forever.

[william]

i agree with you there but it is a turbo charged vehicle and requires thinner oil i would use what they recomend til 90k at least thats when the major service is tbelt tensioner plugs coolant oilfilter pollenfilter brakefluid airfilter and gearoil upon request at your own cost

[Kai]

yeah. Ill just get 0-40 i guess.

[Jmac]

10W 40 magnatec for the Pog mate no dramas there - i believe they now do a 5W40 which will be a great oil mate one of the 2 - thats my opinion.
I may be biased when it comes to Castrol though. Lots of good oils out there having said that i wouldnt use o weight though.

I prefer mobil1 because castrol isnt fully sythentic.

Mobil are the only actuall fully sythentic oils.

[Jmac]

And your point is???? You seem to know enough about the oils why ask the question???????

[Kai]

I was asking for rating of oil to use for my 75k thousand service...

I stated that 0-40 seemed very light. And that i thought maybe a 10-40 would be more suitable.

I may know alot about oils. But that doesnt make me know what oil to use in my car.

Any reason why a 0 weight is not good? Would you say that it is not good for the engine or more that it does not make a difference between a 0w and a 5w seeing we live in a hot climate?

[Veee1.8t]

so do we use a 0w40 or 5w40?

[Jmac]

Ok its more important to use 0w or 5w on engines with variable valve timing as heavier oil can slow down the operation of the vario cam. Turbo engines from experience when they get up the ks turbo spools quicker with the lighter weight oil, im happy using Magnatec on Polo but if you are stuck on fully synthetic if you have been feeding the engine that from day dot thats the go - sorry for any confusion earlier post. I had an A4 APU 1.8T have 10w40 Motul all its life and the owner decided for winter we would do 0W. When the engine got warm the oil light came on - too thin. And the thing was a handfull as it had a Ko4 and spooled up quicker with the 0w 40. Now back to Castrol on this particular engine we then used 0W60 Castrol and it cured it.
Remember the first prefix is for when the engine is cold (resistance to flow) and the second is for when the engine is warm so up the ks 0w40 is a bit thin IMO. If you like the idea of 0w then go the Castrol Edge 0w60 and Supercheap is doing great deals at the moment, with the Easter sale and all.
Also heard of a Daewoo Nubira non runner due to the wrong oil, it pump up the lifters too much and opened the valves off their seats. after a few flushes it then ran when the oil pressure had settled again. Oil is a very interesting topic, and there is too many good oils out there now, its your preference but just bear in mind the weighting.

Cheers for that, good to know, my engine is still new (13000km) so 0w40 I think is good for now. Once around 75000km plus thought it seems like a 5 or 10w would be the better option.
