Service interval for low mileage

Our oil mostly sits outside of the engine. I can't see it making a bit of difference with a modern oil to be honest. Sitting in a plastic bottle or most of it sitting in your oil tank.

I'm not going to break the cycle, but I can't buy that a car doing less than 1k a year needs 10L odd of fresh oil every year; Especially when during use each of those litres has actually done so little work inside the engine itself.

Heck, the 'new' oil you put in could even be older than the stuff you take out if it's been in a warehouse for a while :grin:
 
It's not so much the age, but the fact the oil has already taken in contaminants from those 1000 miles of running... and if the journeys have been short then the car will have been on its enrichment cycle more & the oil would have spent less time 'hot ' so could be less clean than you think

Each to their own, but I change the oil and filters on my 911's each year no matter what ... I also try and do a minmimum 40 miles for each journey too
 
With you on avoiding short cold runs. The main reason my mileage ends up so low is that the miles covered are occasion miles only. Usually single trips of 100+ miles getting nice and warm. Unfortunately my opportunities for 'occasion' miles are few and far and hence annual mileage is stupidly low.

Exactly the same for me - for the sake of £300 or so (OK that's not small change, but running an older sports car is never going to be cheap) for an annual 'minor' service - it keeps the regular stamps in the book too which despite what some people say, could make soooooo much of a difference come sale time.

Honest John :floor: What about the fully synthetic long-life oils that allow engines to do up to 30,000 miles/2yrs between servicing :dont know: I've got an Audi on that service schedule :roll:

I'm dreading to think of some low mileage examples where the owner has nipped out for a pint of milk and newspaper at the weekend. There'll be more coke in it than my great aunt's bunker who used to get free coal from the Coal Board :what:

All that keeps me doing it.
 
:D Honest John isn't my usual source of reference .. but even he talks about low mileage cars having oil changed more often than normal mileage ones

I've been told over the past 25 years of aircooled VW's & Porsches to keep the oil 'fresh', as remember our cars are actually oil cooled as well.

I service my 2.4 myself, so yesterdays oil change cost me a grand total of about £80 incl posh filter & 10lt's of Valvolene VR1 .. stamped service book not required


964 gets done by my specialist
 
Interesting reading all that. I had never even considered that low mileage cars should be having an extra oil change every year!
 
The one tip i think is very important with low mileage 993's , which i never see mentioned is the changing the secondary oil filter,
the one in-front of the wheel arch, behind the wheel arch liner
this is changed on a 24,000 mile service, but not on a 12,000 service.

the problem i've seen on many occasions, are low mileage cars having a succession of 12,000 services,
the secondary filters never changed,

But what i ve seen on many occasions is the filter rusting through, the car loosing all of its oil and in one case resulting in an £8,000 engine rebuild.

all for the sake of a £15 filter.

Also not all dealers wax oil the filter
