Thicker oil advice please

[zeroasylum]

Car is MK4 golf 1.6L engine code AVU

My car is burning a small amount of oil on acceleration once warmed up and so smokes a bit I know it’s the valve stem seals but wont be able to replace them till at least December as way to busy at work to do the job and will do the timing belt water pump etc then.

I currently have 5w40 in there but it is using it up way too quickly. I put in an addative (basically thicker oil) which has helped a lot. Would using Castrol high milage 15w50 damage it as it might be too thick or will it be ok?

Many thanks

Try 10w-50 (penrite does one). You need the cold start "runny-ness"

5w40 is way to thin for that engine anyway so may not even be the valve stem oil seals, just that the oil your using is too thin for that engine even with low kilometers...i would go for a 10w40.. which is vw recomended .how many kilometers has the engine done out of interest

I use a 10W40 semisynthetic in them. Seems to keep the oil consumption down.

Thanks for the advice. The car has 166000 KM on it. I think I just used 2 thin an oil. Will do a change on the weekend. I dont have a genuine vw oil filter for the change. Is that ok or should I buy a genuine one.

Many thanks

Spend a little bit extra and go for the full synthetic 10w40..Its 15k service intervalson vw's and good quality full synthetic will not break down within this distance unlike a semi synthetic..vw502 vw504 vw spec is ideal for that Golf..

Try HPR10 by Penrite which is 10w50

5w40 in a 1.6 with over 160k is a little on the light side

Heh, I ran 504/507-spec 5W30 (because free) in a 2.0 with 120,000-ish Kms on it once.

Drank like a sailor.

So is 10W40 or 10W50 better for this car with this milage?

I'm using 10W50 lemon in my GTi, it's at around 150xxxkm's and seems to be fine, I flush and refill every 5-10,000km though.

Thanks mate!

[Euro Remaps]

for that golf 10w40 is fine as the engine doesnt get hot enough to need a 10w50 like a gti would..
RM86 what oil do you use in your gti ? semi of full synthetic ?

[RM86]

Full synthetic buddy
