I bought a 2007 Hummer with 34,000 miles on it. Is it a good idea to switch to Mobile 1 synthetic?

Also, what oil filter do you all recommend?

 

I just got an 06 with 24,800. I did my oil last night and put in Royal Purple with a WIX oil filter.

I don't think with 34k miles on your truck switching to synthetic will be a problem.

Check your tranny fluid while you're at it. Mine was 1 quart low with no signs of leaks.

 

Synthetic oils are great and so are wix filters.

 

I've heard the same thing & have started using synthetic on my Ninja & Wix was a name dropped by multiple individuals.
On the Tranny... I ran across a thread & have since lost it regarding fluids & possibly improving gas mileage... Can somebody help me out with that???

 

I can't seem to get any reply's or responces on any of my posts regarding help & opinions!!! WTF?!?!?!? I thought this was a sight for passing idea's, past expierences, advise & general CHIT CHAT about our favorite "LIKE NOTHING ELSE ON EARTH" TRUCK/TANK!!!! I am torn on Castol, Mobil 1 or Amsoil!!! I've decided to go with a WIX filter but need to get some advise stat!!!! PLEASE... SOMEBODY respond & give me some GOOD solid direction/feedback!!!

 

Not sure if you've started other threads as well, but if not you might try starting a new thread of your own.

Most of the time a bread demanding help will only get you the opposite.

Also the search feature allows you to search through all the past posts ever made. If you're not getting answers it could be that there are tons of the exact same questions and a search would yield you answer

I don't have any clue as to the anwer re: your tranny fluid.

As for oil I chose to go royal purple for the life of my hummer. Oem tranny fluid and oem transfer case fluids since I'll be getting the extended waranty when mine expires.

I've used mobile 1 and amsoil a lot and have always read good things about both. With amsoil you can become a dealer and get a discount which could save you money. It's a real simple process.

Good luck.

 

I have a ton of experience with 06 and 07 H2 oil changes. I run 5w-30 Mobil 1, same as in my Vette. And a stock GM oil filter. Fram is junk, and so are many others. The OEM is a good filter. Not sure who it is made by, but it works.

Remember the 11 lube points also everytime you do an oil change.

Works great. The new Mobil 1 synthetic seems to have improved over the years (I have used it for 16 years), or the GM engines got better in using it. i.e. Mobil 1 no longer scores valve guides, etc. on GM V8's

Go for it!

 

What has your experience been with Royal Purple?

What lube points and what kind of grease do you use? Not sure if I'll be changing my own oil or not but it would be nice to know what to lube up should I choose to do my own oil.
