[Vwdiesel] Re: amsoil and oil-getting OT

Wed Jul 23 11:33:18 EDT 2003

A couple of things, (I am not an Amsoil dealer, but do use their product in
my TDI due to lack of oils here for it)

Audi cars go 10000+ miles between oil changes, including the 1.8 turbo. Some
intervals they don't even change the filter, just oil! This is their own
service shedule that is free for the first 50k miles. Yes, they use
synthetic Castrol 5W50. Clearly you can go alot longer on todays
oils/engines then people once thought. Same with the TDI, 10k intervals with
EGR!

Amsoil stresses using their own filters (oil and air) for extended drain
periods, using the bypass filter you could extend as long as the analysis is
okay, some people are going lifetime (300k miles+) with engine oil (changing
filters though)

Amsoil does not make a filter for VW diesels, Hastings does which is not
recommended for extended drain intervals (only SDF filters apply), infact I
am not sure they make any diesel oil filters (for cars that is).

Everything that I have read at the tdiclub seems to support the fact that
oil rarely breaks down, the by products that build up are the reason for
changes. I have run winter beaters that would never see another owner
without oil changes for long periods of time, like 30k miles winter driving
on regular oil, no problems (gas VWs), it would seem the industry is taking
us for granted with oil changes. I would not recommend this but I have done
it and never burned out an engine or caused any damage (took engines apart
when finished with car)
If you change your oil every 3-5k miles, your engine will clearly outlast
the rest of the car and will probably die from some other cause, like rust,
a failed timing belt, overheating, oil starvation, failed emmissions, not
related to oil changes but lack of maintenace or abusive driving. There is
no demand for engines around here for cars over a certain age, the body
rusts out before the engine dies!
Most people could save a bundle on oil changes and invest it in rustproofing
and car washes so the rest of the car lasts as long as the engine!
Enough babbling
