Finally got my new(to me) 2004 Silverado Z-71 w/5.3 home. 19,890 miles and
Pop always took it to the dealer or Jiffylube(pfft!) for oil changes. I plan
to do my own _IF_
4x4's aren't too difficult. This one has the Z-71 off-
road skid plates, according to the window sticker and never having owned a
4x4 before I don't know about access-the filter looks easy from looking at
it from above but I haven't been underneath yet to see where the drain plug
is located. Will this be as easy to do as my '91 2wd truck?
So which oil(viscosity) and filter is recommended?
Is 5w-30 semi-synthetic Castrol OK? What about 10w-30-any advantages? Also,
would full synth be better? 5 quarts or 6?
I plan to use either Delco, NAPA Gold, or Purolater filters, are there any
other brand(s) I should consider?
Same question applies to air filters(has the hi-cap air cleaner.
As far as trans filter and fluid-too early to change the yet? Also, what
about the diffs and transfer case?
Sorry for all the questions but Pop left the owners manual at their summer
home and it'll be a while before I can get it.
Thanks in advance,
