Morning all,

i was dropping friends to the airport on friday night and i did a 400 mile round trip. I was flying it mostly around 80 ish . I must admit that on the way home i had it sitting at 120 mph for a good half hour on the motorway !

The next day when o started up the car, a service indicator came up saying "service in 600 miles or 124 days" . I was stunned as i only service it 4k ago and used long life oil.

I checked the oil and it had indeed used a fair bit (About 1ltr) during the previous nights spin. As i had checked oil before i left and everything was fine.

Does the fact that the long life oil is so thin, does it burn easier ?

Has anyone experienced such rapid burning of long life oil ?

Has anyone else had the service indicator come on so quickly after a service ?

Thanks

Not indeed, it seems strange to me.

How many km has your VRS? Mine used more oil in her first thousands kms.

just approaching 37 thousand miles

I don't think that its coincidental that the service light came on eventhough i never got it reset after the last service.

I think the trip burned the oil, changed the vicosity of it and set the indicator off. There is a more pronounced burnt smell of the oil and i have since topped the level up with the same oil in an attempted see whether the indicator turned off, but once it activates it may need to be reset at the garage.

I've heard of touregs burning long life oil like theres no tomorrow, but i've never heard of any reports of the passat, golf or octavia with the pd 170 burning so quick. ? ! ?

IMHO your oil consumption is excessive.My car ,with 56,000 kilometres on the odometer,burnt half a litre of Mobil 1 formula esp on a 2,400 kilometre trip at very high speed,meaning over 200 kph.

Which brand oil are you using?:)

What do you mean you didn't get the service indicator reset after the last service. If you didn't it might have hit the age mileage limit and be calling you in for a service based on that.

If you want to DIY service etc you probably want to switch to fixed servicing intervals so you can reset the service indicator by the dash. buttons.

Yes i bought it @ 26 K miles, serviced it @ 33K and plan to keep it on a regular service of 8k from now on instead of variable which it was on. But the computer still assumes its on a variable, so @ the 40K mile service i'll send it into the garage to get a full service and the brake fluid changed. as well as getting the service changed.

By the way, i used AC DELCO long life oil, VW spec . its .505 or .507

It could be normal!

Service warning comes on when you switch on ignition when miles to service is less than 800miles and it only shows to nearest 100miles. Could be that when you set off on your home leg, miles to service was 850. 200 miles will drop that to 650 which would cause the warning to come on showing 600 to go next time you start up(numbers probably not right but you get the idea)

On variable service the indicator doesn't, I believe, measure oil quality - it uses an algorithm that decreases the miles to service according to how you drive; so 100 miles at 120mph for example could reduce miles to service by, say, 300miles to account for the hard work the oil has to do. Likewise short journeys on a cold engine also reduce the miles to service by more than the miles you travel so a 5 mile commute where the oil doesn't reach full temperature could knock, say 20 miles off the miles to service. On the other hand driving 100 miles at 70mph may only knock 80 miles off the tally. Those numbers won't be right and the calculation is much more complex but I think that is the rough principle.

Thanks for that.

It'l be fine until 40K miles and then i'l give it a service and if "shes" good, a surprise !!

Remap

Ok for service indication, but honestly about 1ltr oil for a 400 miles trip would be too a high oil consumption and reiterated fill-ups for my driving needs. It depends on how often and long you drive your Octy.

I'm thinking it might be the oil itself. I went to a VW sepcialist and bought AC DELCO.

The next time, i think i'l do a bit more research myself and not trust the motor factor that at the end of the day just sees €€€€ when you walk in through the door..:thumbdwn:

Would you recommend a good long life oil ?

I do appreciate that there are big brands out there, but sometimes just because you have a sticker on your container, doesn't really mean you've bought the better quality...I've trusted this fella for a few years now, but this was the 1st time buying long life vw spec oil. . i had a pd ASZ 110 previously. I think he may have let me down this time. !!

Remap

If anything a remap would give more problems , flexing the crankshaft more with incereased torque for one. Probably not great for the dual mass flywheel assembly if your're putting more torque through.

Would a remap, reduce the possibility of burning oil?

I'm considering the possibility that it is the oil itself that i purchased from what a distributer that i trusted for years but as a replied in a previous thread, may have just seen the € sign my head.

I'm thinking of waiting until the 40K miles mark and put her in for a big service and switch the indicator to fixed from variable because i don't do huge mileage !

Thanks for your input
