All I have ever used is the recommended 5w-30... switched to mobil 1 at very low mileage. Some oil change jock told me the 5-50 synth would be even better. Of course, it is on for cheap at the big box store... My pal has a new Chrysler Crossfire, and it takes 0w-50 synth if you can believe it... Any advice would be appreciated, before I pour this stuff in... Thanx

Nope. Don't do it..... Go with the factory recommendation, preferably some synthetic or high-premium dino oil. But, go with the factory recommendation on the oil weight.

Thanks. I did my homework while waiting for responses on here. Then, I went and bought the usual: Mobil 1 synthetic 5w-30. Poured that stuff in the crankcase and went for a drive, hehehe :thumbs:

The thinner synthetic's 0-30, 5-30 and 10-30 will give you plenty of protection and will not steal hp like the heavier weight oils.

I use 10w30 Mobile 1 now. (Never gets very cold in NC). I have heard really good things about Mobile 1 Truck and SUV 5w40 and may use it when i have much higher miles on my truck. Say, over 100k.

 

I would only sugggest 5w50 if you have severe oil consumption.

I wish I had the time to sit down and explain it, but with twin 7yr girls, work and night college classes I just don't have that much time. Especially to explain it and make it easy to understand.

 

Check out Bobistheoilguy , it has a ton of info and it is easy to understand. :cheers:

      Stabilitrak conversion to Z71

      By teamjnz · Posted

      Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks

      OCI, not when but why?

      My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      Tranmission stays in Low

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.
