Nexus,

Is your 95 a 1/2 ton 3/4 ton?  The easiest way is to look for the RPO code in the glovebox (this is a sticker on the inside of the glovebox with a bunch of alphanumeric "codes").  For the rear end ratio the RPO code will start with a "G" here is a list of most of the rear ends in the GM's.  Most likely you have either a 3:42, 3:73 or possibly a 4:10.

Here is the list:

GH0 AXLE REAR, 3.54 RATIO

GH2 AXLE REAR, 2.29 RATIO

GH3 AXLE REAR, 2.77 RATIO

GH4 AXLE REAR, 2.92 RATIO

GK9 AXLE REAR, 4.63 RATIO

GL3 AXLE REAR, 6.17 RATIO

GM1 AXLE REAR, 2.59 RATIO

GM3 AXLE REAR, 3.45 RATIO

GM8 AXLE REAR, 2.56 RATIO

GQ1 AXLE, STD RATIO

GS4 AXLE REAR, 3.70 RATIO

GTY AXLE, WIDE TRACK

GT4 AXLE REAR, 3.73 RATIO

GT5 AXLE REAR, 4.10 RATIO

GT7 AXLE REAR, 3.33 RATIO

GT8 AXLE REAR, 4.10 RATIO

GU1 AXLE REAR, 2.41 RATIO

GU2 AXLE REAR, 2.73 RATIO

GU4 AXLE REAR, 3.08 RATIO

GU5 AXLE REAR, 3.23 RATIO

GU6 AXLE REAR, 3.42 RATIO

GV2 AXLE REAR, 5.83 RATIO

GV4 AXLE REAR, 3.36 RATIO

GV8 AXLE REAR, 2.72 RATIO

GW4 AXLE REAR, 3.31 RATIO

GW9 AXLE REAR, 2.93 RATIO

GX3 RATIO,TRANSAXLE FINAL DRIVE 3.33

G5O SPRING REAR, HEAVY DUTY, VAR 1

G51 SPRING REAR, HEAVY DUTY, VAR 2

G52 SPRING, RR, 15000 LBS

G60 SPRING REAR, AUXILIARY

G66 LEVEL CONTROL, MAN, AIR

I have mine for my '98, but I think we have some different options.  Easiest way is to take your VIN #, to the dealer, or a Chevy dealer (you never said if you got the new truck from a dealer or individual?) and they can punch your # in their computer and it'll printout what every code on your truck is for, like window and seat styles, the GVW, fleetside or stepside, paint, alternator amperage, speaker size, brake types, etc.  And it should be free-

Nexus,

Glad you found the rear end ratio.  Here is the link that will list most of the other RPO codes that are on that sticker.

      Oil Consumption

      By KARNUT · Posted

      No I didn’t watch a video of a person who analyzes oil for a living explain general oil usage. For clarity I did ask my brothers one who runs our equipment business. The other who runs our old ROW business about oil usage. Nothing has changed since I retired. Their personal vehicles or work vehicles use no oil. Not enough to see on the oil checking device. Then I pondered. I like to ponder. In this extended oil changing world with oil change countdowns or lights. If engines used say a qt every 2500 miles or up to even 4000 miles. With oil changes reaching as high as 15000 miles. Normal for most people is eight to ten. Vehicles should potentially be seizing up all over the place. Especially in hilly terrain. Just how many people actually check their oil? Maybe 10 percent. Those are the people that probably change their oil early. I like to research used car listings. I have five favorite dealers I check. They all list carfax with their listing. It’s rare to see vehicles with anything but extended oil changes. Transmission service, forget about it. I’ve seen Honda and Toyota certified vehicles up to 100K miles and ten years old. With nothing but normal maintenance. Isn’t nice we all have different experiences and believe our way is the best. You certainly get backup for whatever you believe. Life would be boring otherwise.

      RUMOR / INSIDER: 2027 Silverado Dealer Reveal NEXT WEEK

      By RobbertClaus · Posted

      Interesting rumor. Dealers near me have been tight-lipped so far, but if this reveal actually happens next week, I'm really hoping they finally give the HD a proper interior overhaul. The competition has been eating their lunch in the cabin department for a while now.

      Oil Consumption

      By Chuck FB · Posted

      There are a few good takeaways in that video that pertain to this thread, certainly the possibility of the oil control rings having buildup, the fuel injectors and how clean or not that they are ending up affecting the pistons rings carbon buildup, and the fact that its normal up to a point for a given engine to use some oil, and that the oil quality that is being utilized is part of that ring clogging up issue as well.   I was talking with a neighbor yesterday who has a baby LZ0 duramax and he had bought it slightly used but it does consume some oil and he has switched over to 5W-30 Euro spec oil and in this case that never made a difference in consumption over the factory 0W-20 recommendation. He finds it uses a quart in about 3500 miles and as he goes a ways over that distance he adds oil to full and goes another 1000 miles or so and then changes oil and is typically at 40% or so left on the oil monitor at that point with his use case of quite a lot of highway miles and more limited in short run use. I don't know what other LZ0 engines are doing for oil consumption but that is what his is doing.

      Oil Consumption

      Ok well I guess Lake disagrees with me on a few points. I call oil consumption pretty basic. Rudimentary. He calls it "really complicated." I think 1qt consumed in 3k miles is a lot. He says that's normal. In 22 minutes, he'll use his natural talent to explain oil consumption to anyone watching this video. He covers everything from obvious engine damage to how normally functioning healthy engines consume oil by design. Lake explicitly states how you drive will impact oil consumption.   Shut up and watch:
