Superb 2.5 tdi service interval

rotodiesel · 09-07-2008, 23:03

I work in the commercial diesel engine field. You can't compare commercial oil change intervals with those for passenger cars. For a start, no VAG car diesel engine has to my knowledge a bypass filter.

I think Lummox has hit the nail on the head. These cars are designed so that the average punter just drives until he sees a red light. This usually means you damaged your engine 100 miles ago.

He also makes a good point about the level sensor. Last time I did an oil change on my AWX I thought I'd test it. When refilling with fresh oil I set the (stabilised) oil level carefully to the bottom bend on the dipstick and drove the car round the block. No red light. I have to say I then bottled out and filled it up to (just) the top bend. I wonder how low it has to get...

I'd like to get my hands on the VAG moron who decided black would be a nice colour for the dipstick on a diesel engine - it beggars belief.

having read this thread.....i had the long life oil service genuine quantum 5w-30 and filter change along with engine flush and my skoda approved garage did it for 80 quid and no labour charge, which was better than 120 from main dealer......smoother engine running too....although it was smooth before.....or maybe its my imagination....but for the sake of a few quid twice a yr and do ones own servicing ie brakes and tyres and fluid changes, i cant see why the car cant go on for ever like these lorrys do

Plenty

Plus there aren't many that don't do 100k per year.

I've had a 2.5tdi auto from new in March07, and it's currently at 16k miles. Every now and then the Maxidot calls for more oil (no red light) and I then put in 0.25 litres of the specified fancy stuff, which always takes the level back to max on the dipstick. So far I have put in 1.5 litres since new. I'm assuming that this is normal consumption, and that at some stage over the next 6k miles or so the Maxidot will tell me it's first service time.

Humbug.

My 2.5 TDI never has an oil top up as I have the car serviced annually with an oil and filter change at the 6 month stage. I do about 5 to 6k between oil changes (12k per annum).

I'm at 40+k atm, and never needed to add any. I'm sure you're right about the service though.

I couldn't agree more, although I suspect even our friends at Wolfsburg aren't the only ones.

Hope you've had a couple of oil changes in 40k...
