We bought a new OBW last year, the L.L.Bean edition. It's my first new
car in...wait for it...37 years! Everything in between has been
purchased used (don't you just detest "pre-owned"?).
I know that oils have improved greatly and engines have changed a lot
over the years, so thought I'd ask about oil-change intervals for this
vehicle.
We rarely find ourselves in stop and go traffic; we are usually moving
along at 30 to 70 mph with the stop for the occasional stop light/sign.
With that sort of driving, I felt that an oil/filter change every
4,000 miles would be more than adequate. Do list readers agree or
disagree???
Eventually, we will change to sythetic oil and that leads to me second
two questions:
What's the optimal mileage for the switchover. Wait until 10k, 20k,
longer?
And is pure synthetic best or is the petroleum/synthetic mix better. I
have heard a very persuasive argument made for the mix because it
absolutely will not foam whereas the pure synthetic can indeed foam.
And, of course, foam indicates the presence of air and where there is
air, there is no oil and no lubrication.
Thanks,
Gunny
