What brand engine oil

[Lucas_R]

Yeah I think I’ve been overthinking it. That’s what I thought to myself as well - I’m sure they did. I might look into getting my own oil to supply them next time or just check with them before I make a booking.

Just as important to me is not leaving the oil in the engine for 15,000km. Too long in my opinion and not good for engine longevity. I get the mechanic to service the car every 12 months (log book service) and then 6 months later ill do an oil + oil filter change and check over the car for piece of mind. 12 months is a long time between oil changes and a check over.

You are wasting money as overseas they have a 30,000km oil change regime with the SAME OIL

And Id love to know how long those engines last with such a long oil change interval. No thanks.

I respectfully disagree with you - although we are all entitled to our own opinions. Service intervals designed by manufacturers are not designed with engine longevity in mind. All they want is to get through the warranty period which a new engine would have to be unlucky to not survive with long oil change intervals. Once you are out of warranty, they dont care if you have engine issues. They want you to buy a new car - that's how they make money.

Think of all of the transmissions these days which do not have a service schedule because the manufacturer say its filled for life. Life does not mean 20-30 years, life means about 7-8 years then your transmission shyte itself and instead of spending thousands to fix your broken car, you go and buy a new one. A good example of this is the ZF transmission in my SQ5. Audi say its filled for life....but ZF, who make the transmission say they recommend an oil change between 80,000-100,000km. I know who's advice I will be following because I want to minimise the chance of having my very expensive transmission shyte itself because I didnt do an oil change at the specified interval.

Plenty of videos on Youtube etc showing cars which have not had engine oil changes done for 30,000-40,000km. Its not pretty. Think of all the fine oil lines and oil galleries inside your engine (turbo feed, oil squirters under pistons, variable valve timing systems etc) and how small those feed lines are. They have very little tolerance for dirt/carbon etc due to poor oil changes.

It costs me no more than $100 to do my intermediate oil change and it gives me piece of mind that my engine always has good quality and fresh oil in it.

The point I was making was that the OP obviously doesnt do 15,000km a year but like me does the service anyway. Then does one at 6 months again. Our cars do about 5,000km a year and Im stuffed if I will do a 6 month one. No car needs an oil change that often.

But then my Landcruiser was every 5,000km but is a vastly different animal to a VW.

I also would be reluctant to do a long service regime but we dont do we and neither do VW advise it for AUS but the oil obviously "can last" a lot longer without much harm.

You are guessing with no basis of fact, get some tests done and come back with some real results.

Sure ill just go off and spend thousands of dollars and many hours of time proving this information just to satisfy you.

Im not guessing anything, this is well known information. The vast majority of us use our cars in what is described as “severe conditions” in the owners manual (lots of short trips, lots of cold starts, hot/dusty environment, lots of idling, stop/start traffic etc) and in these cases they recommend 6 month or 7,500km services.

I’ll stick with my 6 monthly oil changes knowing I am doing the best I can for my engine, as it satisfy’s me. Even if it is considered overkill by some, it only costs a small amount of $ to do as I always buy the oil when its on special, and gives me satisfaction to do some basic maintenance on my car and check everything over while its on stands.

Id much rather have an over-serviced car than an under-serviced car.

The only true way to find out about the condition of your oil is an oil analysis.

But for the sake of $100 and an hour of your time, it gives you peace of mind.

For my own MkV GTI, I change every 7,500km as by then I've already topped up oil twice and due to top it up a 3rd time.

I use 5w40 502/505 which I can buy on sale for $30. Mann oil filter is like $10. So $40 for me.

I do the regulat services myself (and leave the harder stuff for my VW specialist) so going under the car gives me a chance to check for leaks, split hoses, CV boots etc.

My dealer used that version of valvoline for the first 3 services in 2009/10/11. Here we are 206,000km later and the engine still runs beautifully with no oil usage. It is 504/507 compliant.

I've done UOA twice on the 15k service interval (60k & 120k) and both times the oil tested as-new in terms of viscosity and additive pack, etc. This is with 70% highway driving. If you operate under any of the severe service conditions then it might be a good idea to pull it back to 10k km.

NB: 15k/12m service intervals are with VW502/505. Variable/2yr is 504/507. So in Au we over spec the oil for the 15k service interval.

Tiguans here have a sticker under the bonnet that says 504/507. We do not use the new grade 508????

So same as other models Enviro+ or Castrol professional III or as below from shops
