Engine Oil

strange could have sworn they recommneded castrol in the manual.

Any good quality 5w30s fully synthetic oil will do! I change mine and filter every 5000miles since new !!! I love my engine and i know if i change the oil more than needed it will stay gleaming! It can only be good for the engine and costs next to nothing!

ive been using castrol edge sport every 7500kms up to 60.000kms, just changed oil to castrol magnetic 10w 40.. i think its good enough oil considering engine is run in and summer is coming up and much cheaper as well..

Penrite HPR5 for the win IMO, and really as ChrisuK states there is no false economy with regular intermediate oil changes

Castrol is not only reccommended in the manual, it is also imprinted onto the oil filler cap.

I'm running Edge Sport 5W30 and no complaints sofar

For the extra $10 it costs to get the 5w-30 Castrol Edge I think you're crazy not to get it.

Sure, I can understand not seeing the value between $70+ of Mobil 1 compared to $50 of Castrol Edge... but you should at least go a full synth for any turbo car

Castrol Edge is verry good oil if you go drive on a cirquit.
for daily use it's not the best oil.
it's made for driving on constant high RPM's and the oil is really is good when the engine is hot.
it will also keep constant temp. when you push it to the limit.
i use Mobil 1 because it's more forgiving for colder engine start. (wich is important)
and for the rest its about the same as Castrol Edge

[mikepologti]

funny, i thaugth it wasnt a good idea to change engine oils once youve been using one?

[instigator]

does not matter alot, if you don't change every time you give it a service..
VW uses Longlife oil, not bad oil, but it's made for making more mile's.
and a GTI is a sportscar and most of the people use it that way, so youre better of with better oil then longlife.
so if you change to something better, it's better for the car

WTF? I realise English isn't your first language but your info on Castrol Edge (which viscosity are you referring to?) is just wrong.

VAG engines that require a VW502.00 spec oil will run just fine on a daily basis if Castrol Edge Sport 5w-30 is your oil of choice.

I think his english is fine, and makes sense. His views may be different... or may have the wrong information. Don't really need to start your reply with WTF...

anyways, engine oils. Mobil 1 is nice, but I hate how they come in 4 litre packs in New Zealand, I always ended up buying 2...

I am happy with Castrol Edge, but trying Valvoline new fullsynthetic one this time. But I believe, as long as you change 'decent engine oil' regularly at 5000km or 7500km, that's the best thing you can do..

It's like a having the best nappy on a baby, and changing it once a week, compared to decent nappy getting changed every day.... - well not the best comparison... but you get the point.

And as for magnatec - non-synthetic ones maybe more beneficial when you first get the car to up to 10000-15000km (and of course replaced at regular intervals), but to use full-synthetic from then on. This would help with the initial engine wear to get rid of all new excess bits to be removed, then to coat it with full-synthetic to prevent further wear. That's what I do with all my brand new cars. Polo GTI I got at 19000km so I haven't had a chance, I think it had a long life oil till 16000km!!! driven by a lady, serviced once. But then my engine performs well with no oil consumption at all.

I have been using Castrol Edge 0W-40 from day dot. Working well so far after 52,000km.

Nulon 5W-30 engine oil

just thought i'd jump in and say that on weekend i changed my oil in the black polo gti(no longer under warranty so i'll save the money and do the services myself).

after much research on this forum looking up engine oil stuff, i went for nulon 5w-30, fully synthetic. its aussie and it meets the the vw standards. im dam happy with it so far, but i've prob only done 50km in it since changing the oil. seesm to idle smoother, at cruise speed the engine has a nice crisp engine rev which wasnt there with the dealer oil (i dont exactly know what they used, but i think it was castrol something). my first time with nulon too.

i know FUCHS make good stuff too, so i'll prob give that a crack next time.

Putting fully synth oil in a Polo GTi and then changing it every 5000km is just a waste.

For example. A friend has a MX5 SP (1.8L turbo with 140rwkw) and gets it serviced by the book. 10000km oil changes using dealer supplied oil (semi synth magnatec). It has 140,000km+ on the engine with no issues.

Castrol Edge is verry good oil if you go drive on a cirquit.
for daily use it's not the best oil.

that sounds like unsubstantiated rubbish to me

synthetic vs semi-syn vs mineral

its arguable that street driven motors have to deal with a wider range of variables and therefore stresses, temperature etc when compared to a circuit race motor (always driven to extreme - which is what they are built for). i can state from experience (i have built engines for street and track although not VW/audi engines) that its ALSO in the street car you want the good quality oil in. and 10K or a yr is a good life span for a good quality oil.

its prev been said in this thread- go for the vw approved oils and you cant go wrong.
