+1 Changing the oil in a car has got to be one of the easiest jobs going



Nor me.

Some rules I follow :
1) change it often, usually well before the mileage and time are due
2) always change the filter every time with the oil
3) drain it properly and when hot so it flows
4) fill the filter with oil before you fit it
5) don't get stressed about oil types, right grades of same type will mix
6) change oil and filter before winter lay up not after
7) keep a cold engine revs down until warm

I changed the oil and filter on my new +4 at 1000 and about to do it again before 3000, it's cheap and easy maintenance in my view.

Frankly speaking a new +4 has an up-to-date-engine that requires modern service intervals. To change oil at 1000km may be sensible but change of oil some 2- or 3000 km later seems wasting resources to me as service intervals at higher tuned modern engines are at 25.000km or 2 years on my "standard" cars.
Rather not to forget greasing the king pins than changing modern oil too often.

Just my personal opinion.

All I would add is that oil filters increase in filtration as they accrue particles. So although logic suggests that a new filter is best, the science says otherwise. So last Roadster service in 2014 I changed the oil but not the filter.

This advice from a filtration specialist by the way.

each to his own I guess.. I certainly wouldn't go 2 years on the same oil, modern or not. Also I think its driven by a need for economy and lower overall running costs especially for the Fleet market...

Dave logic says to me that filtering clean oil through a filter that has 'accrued particles'(partially blocked?) is questionable..

but then I'm old school.

The filtration man is an expert in his field Steve, where he deals with industrial installations on far finer tolerances than car engine filtration, so I respect what he has to say.

What would be interesting would be a list of oil filter manufacturers, and the specification of their filters, because I doubt they are all the same.

The logical progression of the Dave theory is that no would ever have changed a filter in the lifetime of the car and the filter would have long since ceased functioning and been on bypass - not for me but I'm difficult to please when it comes to caring for my car.

I've seen all these new theories come and go before and in general if it's easy there will be a trade off that catches you out.
Filters and oil are cheap and as hamwich said an oil change is the simplest of all jobs.

Ah but it doesn't follow on to that degree. It only applies to new filters and how they preform in the first few thousand miles.
They should always be changed at recommended intervals, but my conversation with the expert was about changing the filter more often than that..........................

Indeed - plus of course we now have the ability to manufacture engines to extremely high standards. Properly looked after, they will last for truly enormous mileages.

It would be hugely cynical of anyone to imagine that by extending the service intervals, manufacturers are knowingly shortening the service life of their engines under the guise of reducing running costs.

After all, why would they do that? It would mean their engines wear out more quickly than would otherwise be the case, leading to owners having to buy new cars more frequently.

And preferably those with impressive emission figures..
