Maintainance Question

[grilled2003]

What oli would you guys recommend for 2007 Tahoe?
Also, diferential and transmission oil, is it something that I can
just drain and put new one becasue dealer told me they hook
it up to some kind of a tool that pumps all the oil and flushes it
before putting new oil in?
Is this something I should have them do or I should do it myself for about 30% of the price the dealer wants??

Thanx guys

Do it yourself. There are a lot of great lubricants out there. Depends on if you want to go synthetic or standard. Mobile1 or Royal Purple is good stuff for synthetic.

Mobile 1 fully synthetic oil with a filter of your choice.
For the trans. and diff. just leave it alone and change at recommended intervals. The trans. is probably better down at the shop.
