Maths was never my strong suit. :confused: My 10 times table is within my grasp. I don't do too many kms and 10k comes fairly close to 6 monthly intervals.

I didn't know that oil analysis was that cheap. Thanks for the advice.

The only difference is, it's easier to remember.:D
I'm guilty of this on the shopping trolley, factory intervals are 14,000km, I do every 10,000km as it's the only way I'll remember.

I'm surprised the TDV6 is only 12,000km. I thought most modern diesels were pushing 20+ thousand km.
My 2000 vintage work car is 20,000km intervals. My 1986 Isuzu is 16,000km intervals.

So if you change it at 10,000km - what do you do when it goes in for its 12,000k service - do you tell the dealer to just do the service but hold the lube? If it doesn't matter why bother - do everything at once.

My L322 is 20K but I do it and the Tdi every 10.Like Dougal said it's easy to keep track of. Pat

If it's still going in for dealer service, why would you change the oil yourself?

Hope this isnt a hijack but I think its relevant to the topic...

I have a diesel (its a high mileage TD42T in a GQ) which in the last year or two has only done a few thousand km a year due to now having a company vehicle.
Still, when it is driven, they are longer trips where the engine always gets to operating temp.

Should I still change the oil according to the time schedule (6 months) or are the time schedules mainly designed to cover against low km, short trip usage where sludging could be an issue? These days, If I changed the oil every 6 months, it would only have a couple thousand km it on it and take 10.5 L and 2 filters every time - it starts to get expensive. If the time schedules arent relevant, what would be the maxiumum 'sump' life of the oil under the above driving conditions?

Maybe it's just me, but if I was changing oil due to time, I wouldn't bother doing the filters.
