The right way would be to do an oil analysis every X miles. Driving
conditions vary so much we'd all be on different schedules for changes.

We used to do that with hydraulic units on the machines. Cheaper to pay
for an analysis than replace 55 gallons of oil that is still good.


for big machines and maybe a fleet of vehicles, but for a single car, it
would probably cost way more to test it than just change it and the
filter.
Kits run $35 to $85 and one test doesn't tell you a lot. You are
looking for changes - so you need a base-line first.
Cheaper on most cars to just change the oilevery year or 12000 Km with
a mid-priced synthetic.
Costs me about $50 on the Kia 3.3 and just a bit less on the 4.0

Â* Funny this should come up just now . Tomorrow we'll be using my
wife's 25% discount for working Thanksgiving weekend at Walmart . Some
of the items I plan to stock up on are motor oil and ATF . Need some
gear oil too . I'll be doing some axle work (re-gearing) and trans
repairs on my truck soon , might as well get the best deal I can on
fluids . And stick it to Walmart as much as I can before she quits -
which if I get my wish will be before the end of the year .
