Title: 150,000 miles on AGU, swap from 5/40 fully synth to 10/40 semi?
Post by: The Dave on 20 September 2011, 00:01
As title really. The engine isn't particularly noisy or anything, but maybe it's my paranoia kicking in, its a little bit more tappetty than it once was. I change the oil every 5/6k and usually use 5w/40 fully synth quantum platinum.

Due to it's age (1999) and milage (150k just about to turn) would people recommend running the decent 10w/40 semi synth quantum stuff? To be fair the old owner used to run that and change it every 5k... but wondering if 1) it'll be better for the engine due to miles and 2) make it quieter?

I'd of course keep up the changes every 5 or 6k :)

Thanks guys.

Has it had the pick up pipe replaced.

I would stick with 5/40 fully synth.

I have no documentation to say it has been done, so it's something I've considered doing.

Truth be told I want to sell the car and buy a civic type R but it is due an oil change, and unfortunately (for me) needs 2 front tyres also... I've always looked after it and don't want to stop just because I want to sell it for something newer :)

Ballache that the prices for MK4's have dropped so dramatically low now mind!

Does it use any oil as in burn it?
If not you would be ok to stick with synthetic.
If it were me, i would probably use 10w40 in it.

It isn't using any excessively, just normal enough I guess, perhaps a little more than it used to use. I don't have any leaks though nor smoking etc. But she is getting on a bit now miles wise.

sorry to jump in, but 'The Dave' you aren't the guy who used to own a red corsa B 1.6 sport by any chance? T51FNN?  :huh:

Go with the 10/40 quantum semi syn oil a VW tech told me after 100,000mls use this grade of oil.

Why would you stop using Full syn?

This old story of when an engine gets to a certain milage just stiff some thicker semi in to shut it up is a bit silly and doesn't solve any problems.

Running Fully Syn oil has its benifits to the engine regardless of age/milage (of course classic cars are differnt)

Keep running fully dude!

I suppose I'd feel better knowing quality oil is in there, true... it's not that noisy anyways, I'm just paranoid, I look after all my motors and just want them to sound healthy :)

Ahh yeah I saw it in that guise on pistonheads! :) Did it treat you well? Gotta be honest it's the best car I've had, was mega reliable (better than any VW! lol), sold it to a lad called Ben 2 yrs ago for 1100 quid and he literally ragged it off my doorstep, I looked after it really and did buy it bog standard then did most mods it would have had before you got it :)

150k is nothing..my 1.8t engine has done another 30k and still has 5w40 (with the correct larger filter..I don't know if the golf has 2 sizes?)

Yeah I also use the larger filters, takes a good 4.5L of the 5L quantum platinum stuff I buy! lol

you got the part number for the larger filter,and whats the thinking behind it? just to have more oil going through the engine? im on 193k miles on my 98 AGU and i use fully synth oil from VW.

also,is having the oil  pick up replaced a major job? im having a big service on the golf soon,and im trying to pre-empt any problems so im tempted to get that done as well.

Around 2 1/2 hours tops, parts are cheaper from Skoda.

The Skoda part number for the pipe is S06A115251 that is for an AUQ but I have been told they are all the same, retail price is £8.23, Oring is SN0282222, £2.16
