We have a 2008 GMC Yukon (5.3L) that has just over 154,000 miles. It does burn a little bit of oil, however, as often as I check the level (sometimes weekly), I hate having to add oil to bring it back up to full. I am thinking about trying Valvoline Synpower with Maxlife or Mobil 1 High Mileage 5W-30 to see if the consumption is reduced or stopped. Which would the forum use and why? Thanks!
Full Synthetic High Mileage Oil

I like Pennzoil High Mileage but recently changed to Max Life because of Pennzoils leaky jugs and the max life seems to be a good oil so far.
Not to make your choice more difficult, but Pennzoil also has a full synthetic Pennzoil Platinum High Mileage option which is a relatively recent offering. This is different from the regular Pennzoil High Mileage in the gold/copper colored jugs.
All three choices are good. What oil are you using now? if you're using one of those brands currently I would say to just pick the same brand's high mileage oil.

If reducing consumption is your goal I'd try Maxlife or Pennzoil HM.
I did not know pennzoil had a syn HM but in any case if its not sold cheap at wal mart it probably won't sell so good
Valvoline Maxlife
Anybody try Castrol Edge HM yet?

I vote for Valvoline MaxLife. Either the synthetic blend or full synthetic. Synthetic Blend is 30%-40% synthetic & seems solid for runs of 7,500 miles.
The full synthetic version is always a good option too.

M1 is also a solid oil ..I havent used it yet but,,
The 5.3 Vortec is known to burn oil. The 6.0 does it as well but not as bad for some reason, maybe the larger piston bore has something to do with it.
A few GM techs I've spoke to have all pointed out it's due to something that has to do with the cylinder-canceling technology of the engines. Cruising at highway speeds, the back two cylinders shut off and the engine runs in V6 mode to save fuel. Something about this whole process causes them to start burning oil after a certain amount of mileage.
Again, I am not 100% positive on this, it's just information I'm relaying from GM techs. I'm sure there's a lot of reading about it on the internet if you search around some.

Either is good. But I'd try Mobil 1 HM first since it claims to do some cleaning and I had some luck with it in the past in reducing consumption...
Pennzoil HM syn or Castrol Edge HM for the win. Valvoline is still just a bit behind imho.

Hi jsjonz01 - You might want to try Pennzoil Platinum High Mileage for your Yukon as it is specially formulated to stop leaks from seals and oil consumption in worn engines. It also provides faster low temperature oil flow, protects in extreme heat and provides better protection from friction. Hope this helps! - The Pennzoil Team

I just put the full syn maxlife 0w20 in the 13 Corolla. Just about to hit 80k. Can't hurt.
Regular maxlife blend 10w40 into the maxima. Last fill was pennzoil conventional high mileage. Hoping to find one it likes best to reduce consumption.

I used M1HM in the past and while it did a great job, I felt like my engine was a little "louder." This is purely my ear and nothing mechanical but both my vehicles seem quieter on Pennzoil HM. I use the old conventional version but they do have Pennzoil Platinum HM now to compete with Maxlife and M1. if it is anything like the conventional version I would recommend that. I'm not due but I will come back with results once I make the switch
