What synthetic oil weight / filter to switch to ?

[MyBlkBurban]

I did search this but still couldn't find a definite answer....

I have a 2004 5.3 Suburban and am doing an oil change tomorrow. I want to go full synthetic - but not sure what oil weight to go with or filter that works best ---

anyone ? thanks

:thumbsup: That's one hell of a deal !

Now what is the best weight to get 5w/30, 10w30, etc... Should I use the same weight in synthetic as in conventional oil?

I put the 10W-30 Extended performance last weekend.
Didn't like the looks of the Mobil filter compared to the WIX (NAPA GOLD) I have used forever, but it came with the deal, and you couldn't get just the oil without the filter. So I went ahead and used it..........

May change it out to a WIX later. Figured it could be as bad as a FRAM..........

I use pennzoil platinum 5w-30 and the pureone or K&N oil filter.

I do m1 5-30 synthetic with the mobil one filter unless that not avail I use quaker with the delco filter. Is it just me or are these filters looking like they need to be supersized?

ROYAL PURPLE - I love em...I know a lot of people out there say there is no real proof but I got a 3mpg increase in a 94 Ford Bronco w/5.0. I use them for oil, rear diff, tranny, anywhere I can put it...its a little more expensive but it is a GREAT PRODUCT

I keep hearing this and I want to try it. I can definitely do the engine oil, I have never done the diff fluid before though.

I use mobil1 5w30 ( which is the same I had in conventional oil) and its fine for me. no leaks or anything.
