Oil change frequency post remap?

When I had my VRS remapped, I changed the oil every 10k as I read that it is better than the 18k longlife service interval.

If I were to get my e350 mapped, would it be wise to change at 10k vs 15k bearing in mind I do 25k per year?

I am happy to do an oil/filter change myself in between dealer visits.

Thanks

Can't imagine how a remap would affect oil changes. Whoever changes oil after 15k on a petrol car leaves it a long time! I do mine every 6k!!

I think it all depends on how and where you drive it if you have a heavy foot and do a lot of round town I would half the manufacturer's service interval if you don't accelerate hard much and do a lot of motorway miles I would do it around 15 k.

Wouldn't the ASSYST system flag up an 'early' change if the oil condition deteriorated prematurely?

Thanks, I'm just keen to insure turbo is kept with fresh oil - a bit of preventative maintenance for little cost

Thanks

Oil is cheap, engines is expensive. I reckon your 10K at most is right.

Extended oil change intervals with 'longlife' oil, like 'sealed for life' transmissions, were introduced to keep down servicing costs and make cars more attractive to fleet managers - lower service costs during their life on the fleets. There's masses of anecdotal evidence to establish that sealed for life = shorter life, and I draw my own conclusions about extended oil changes.

I'd change at least every 10k regardless of remap or whatever.

I'll probably change mine every 4 months, 1 change will be with the dealer (every 15k) as per schedule.

I'll see how it goes for now...

Waste of money. Synthetic oils don't deteriorate at anywhere near the intervals you're talking about. I once came across a mechanic who's car done 250K miles on the same oil. He drove it daily and never changed oil to prove this point. I don't know why you came to conclusion that at 4 months (and even months not miles) is the correct interval. You have done any scientific research to back it up?

Don't most sumps have a magnet for that.

Changing oil too soon is not a good thing...oil stabilises after the first few hundred miles. Changing too soon increase the number of times you are using oil before it has stabilised.

OK, i was thinking of changing every 8k-10k based on 25K+ per year, which is minimum of 2 per year, hence the 4-6 months.
I do a mix of town (london) and Mway (M25 ) and did read that the oil should be changed more frequently if doing short / slow journeys, which I seem to be doing now since I've acquired this vehicle.

8-10K seems a sensible compromise especially if you are prepared to DIY. One potential problem with a remap is the potential for overfuelling in certain circumstances. This might indicate that a shortened oil change interval might be wise.
