First time changing engine oil 2005 Yukon XL

[mountie]

I have been a Synthetic Blend user. But I hear the possibility of oil leakage due to fully synthetics?

I daily drive close to home..... in Florida.....

I want the best oil...... but I am new to this 2005 Yukon 5.3.

( My old truck was easy.... '88 GMC - 350cid)

Any suggestions?

Every vehicle i have owned in the last 25 years i have switched over to full synthetic and it has never led to any any oil leaks or worsening of existing leaks.

 

[mountie]

I believe Syn will be it.

Switched my 2006 to full synthetic at the first oil change into owning at it at like 77,000. Never had any excessive oil burning or leaks.

 

[mountie]

OK..... Motul ? Amalie ? Or good 'ol Mobil 1 ?

My Yukon is an investment..... I want the best - when the more expensive is actually better.???

Same. Everything down to a 1998 went to synthetic. Never owned anything older. Mine's a 05 w/ 140k and the underside is bone dry. Not even so much as a wet spot. Don't think I got the memo that I owned a chevy


I use M1 0w30 ESP, NOT the AFE. Stupid naming but the esp has a better viscosity index and better high temp/high shear numbers.


Don't skimp on the filter. IMO it's your biggest determining factor. I'd rather run a top of the market filter and cheap ass oil to meet a budget than the other way around!

I should add: Stalk Napa for sales on the mobil 1. They have it on sale for 50% off every couple months. It's like 5 or 6 bucks a quart at that time.


Filter wise, there are only 3 I'd touch, but only 2 I use due to availability.

All listed are a high quality filter w/ synthetic media, silicone ADBV, thick case, etc etc. Note I use the longer units rather than the updated shorties.

In no particular order:

1. Amsoil EAO64
2. Fram XG3675 - Wouldn't touch the rest of their lineup w/ a 10 foot pole, but the ultra synthetics stand peer to peer with the amsoil units
3. Donaldson has some part interchanges. Never looked into it since I really can't get them locally

SnowDrifter...... I agree..... I heard, WIX filter is very good too....

I had an '88 GMC w/ 390,000. Always went for the best oil/filter.

I'll check out that 0w30 ESP ( Mobil 1?)

Yea.. Amsoil is good also....

( I hauled an Unlimited Hydroplane from San Francisco to Eastern Washington St, for a race....)

E-Gads...... I had no idea how eastern Washington St was so flat & dry!!

Wix is OK. Not bad by any means, but it's a pretty bog-standard filter. Paper media enclosed by metal end caps. Good quality control, I've yet to see one incur a failure (looking at your, purolator) or otherwise have issues.

I want to like the wix XP because it has mesh backed synthetic media. But the things filter like ass in testing. They just don't perform.

Yeah eastern washington might as well be a different state!!


For what it's worth:

Amsoil EAo

Fram ultra:

Wix standard and XP:

What say you on the Mobil 1 filter?

 

[SnowDrifter]

What say you on the Mobil 1 filter?

On par with wix. Paper filter, metal end caps, silicone drain back valve.

Haven't used them enough to be able to comment on their quality control though

Does "synthetic blended media" mean paper?

Does "synthetic blended media" mean paper?

No, but I rank them with paper in my head. Poor wording on my part

Blended media captures a bit more dirt than paper, better if you're doing longer OCIs. But doesn't really have the flow rate of pure fiberglass media or the filtration efficiency with respect to particle size. 99% at 30 microns. Good enough? Yeah. Exceptional? No

Cool. I read a post from somebody that called Mobil about them. They told him the 30 micron test is based on some standard and their media is good down to 19. Obviously, the % efficiency will go down, too.

Having said ALL THAT........ It comes down to......... Wha kind of filter material I should prefer, and the material is described on the package as..... Wha ??

( besides the known other pluses of how a filter is designed )

Hey all, I suggest Castrol full synth with Partsmaster 61522 (about $5 from rockauto.com) this is Wix 51522 equal. I ordered both, cut open and all items were identical. I think my Tahoe called for the 51045 (short) filter, but prefer the tall can. Did the same with Wix 51258 and had same result with Partsmaster 61258 and use those on my Chevy BB & Olds 403. I got an email from R/Auto saying items discontinued for my vehicles in garage and ordered for $1.50 each, shipped, so ordered 100 61522 & 50 61258. I'm set for life yo. :^)
