'03 Isuzu, Synthetic Oil
Q:
I was
thinking of using synthetic oil, possibly 20W-50 in my 03 Isuzu
with a V-6 engine. Can you recommend brand and input on choice?

A:
Synthetic
oil is good choice for any vehicles engine if you can afford the
extra dollars it cost. There is a lot of good product to select from.
I would suggest a product that is easily found in your area. There is
nothing more frustrating than not being able to get the oil you need when
you want to service or top-off the oil level. I wouldnt recommend
the use of 20W-50 oil in your vehicle; you just dont need that high
of an oil viscosity with your engine and it may void your warranty. I
suggest checking your Owners Manual and follow the oil viscosity
recommendation listed. Also, you must follow the oil service intervals
in the Owners Manual to maintain the vehicles warranty. Some
synthetic oil manufacturers state that you can go longer, more miles and
time, between oil changes than the vehicle manufacturers recommendation.
They will even offer a warranty if you use their oil. Word of caution,
in the event you should have an engine problem dont expect the dealer
or vehicle manufacturer to perform the warranty work. Youll have
to work with the oil manufacturer if their service recommendations are
outside of the vehicle manufacturers during the warranty period.
