I used to use Mobil 5-30 and now use 0-30 M1, I notice a difference.
Timing shouldnt change in 35000, mine didnt change until the belt was
real old but checking timing is easy to do and you dont know for sure
it was ever done exactly, When my timing was retarded 3 degrees, on an
old stretched belt with maybe 70000 on it, I had a major loss in power
and 3-4 mpg loss. You can advance until there is nock but hearing any
is not easy, I go 1/2 degree further and have been safe. Noise is
likely wear from age and hard driving.
Hi,
Its never been driven hard really.
More average use.
On the point of it not been set up correctly when the belt was changed.
I seem to have less faith in folk doing jobs for me now.
It seems there is less and less pride in doing a GOOD JOB these days.
And I don't think main dealers are any better.
I realise its easy checked but I did not feel like spending an a Timing
strobe
for just the occasionally time I may need it.
But all comments absorbed
Thanks
look at my web page. www.g3liv.co.uk
That's what I do in retirement,

Trying to squeeze more miles out of an already economical engine is
like trying to up the hp on an already high hp engine. It can be done
but it gets expensive, if you are getting over 30/mpg highway that's
pretty good. Advancing the timing may add a little bit, but varying
qualities of fuel can lead to possible engine knock. Anyone remember
the octane selector on the old Toyotas? There was a little knob on the
distributer and you could turn to bump the timing forward or backwards.
I changed my timing belt less than a 1,000 miles ago and I didn't
notice a bit of difference between the new and the old.
