Mk5 gti oil

Post by Trishen94 » Tue Apr 16, 2019 10:16 am

Hi guys ...and yes I know it's been discussed but when I try to search it says the search is ignored coz it's too commonly searched

So I wanted to find out which is the correct engine oil for a
2008 mk5 gti bwa 230 000km on the clock ...ive put in hx7 but the guys say it's the wrong oil and will cause premature cam shaft and lifter wear ...so what oil should I use? coz this is what goldwagon gave me

If it says VW 502 approved it should be fine.

HX7 will not be a problem. Your car is not a Diesel with Pumpe Duze injectors. You are reading the wrong thread.

Hx7 and ultra are fine. But they have a high evaporation loss so the boost pipes and intake end up with alot of oil in it. Rather look at a 504 oil or something with lower NOACK value. Should help with carbon buildup on valves.

Yes HX7 meets your GTI spec.

To clear up any confusion:

HX7 for both petrol & diesel engines(VW502.00 & 505.00):

AND

HX7 Pro AV ,specifically for Diesel engines (VW 502.00/505.01)

10w40 is fine, wont do any harm.

1.The spec i.e 502.00/505.00 means that the oil/product provides adequate lubrication/protection required by the VW engine.
2.Mineral & Synthetic Oil (Full Synthetic actually doesn't exist) - difference is the refinement process & additives to the oil and it's benefits thereof.
3.Viscosity (measure of resistance of a fluid to a change in shape,movement) i.e 10W = measurement when cold , 40 = measurement at operating temperature.

Factory viscosity for your GTI (AFAIK) is 5w30 , but because you have a old car (more tolerances) , using 10w40 gives you the adequate protection but means the engine will have to work harder because oil is thicker = more heat , less performance, less fuel economy etc.....

The 40 is Ok for older engines and specially where they are known to have pressure issues which the BWA is. So no harm will come to your motor from that oil.
