Using a bit of oil...normal?

[Drey]

I bought an 03 (LB7) Duramax this last summer. Ran it, pulled/worked it from july thru november without issue. Been dumping oil every 3500 miles or so, probably way on the light side for a Diesel but I want it to last. Since its turned cold this winter I try to let it warm up for 10 min or so or at the very least take it easy for a couple miles.

Ive noticed its using about 1/2 a quart every 2000-2500 miles. Is this normal on these in the winter? Im running Rotella 15-40 and Fram Toughgard Filters.

Im thinking next oil change(bought 200 miles) Im going to throw Lucas in it.

How many miles on it? Dosnt seem really outa line especially if u are beating on it. Leaking any? The breather puking much?(no pcv, has a dump tube)

 

[Drey]

166,000 not noticably puking but you can tell its letting some fumes out by an area on my garage floor not liquid just the vapors Id get Id call it settling.


Just kinda curious, I wasn't losing any oil till it got cold.

This has nothing to do with your oil consumption issue.. But......







Get that god damn fram filter off there!

What he said ^^^^

Fram oil filters are the worst on the market.

Early dmax just has a tube that pukes oil vapor out. Up toward the front/bottom of the motor.

I have heard people (on the internet) lately claiming higher than normal consumption with rotella, and a switch to delo results in little to no consumption.

Might just be an internet lie though?

Everything on the internet is true.

Bonjour.

I have noticed oil consumption with a few different brands and also synthetic vs non. My older higher mileage stuff goes through more synthetic than cheaper non.

Sounds a bit on the too much side but I know the lb7 does use some oil. Take some samples and send them to black stone labs. I'm pushing 11,000 miles on an oil change in lly due to oil sampling. 3500 miles is way too short of an oil change interval on a diesel these days

Yes, depending on usage, 3500 could be way too short or way too long of an oil change interval. Only way to know is samples.

While not disagreeing with oil sampling(has many benefits) the dmax's oil change monitor does a deccent job. It dosnt sample oil or take into account lots of things that are hard on it but it does keep track of how hard u run it and alter it accordingly. Oil sampling occasionally let's u catch issues and if u go with syn oil and extended drains it can save $.

On my 03 and then 06 I just always changed at 1/2 when it told me to. Both of mine had an issue with hard use and over fueling though. I figured gm didn't account for N2O in thier oil use algorithm

I personally ran mobil products and gm filters on mine. And would recommend that and changing when it tells u to unless it sees lots of short trips, hard use, sitting, idling etc.

Oh.....I used fram fuel filters exclusively. Because they were cheaper and at the time rebadged filters(raccor iirc) that were the exact same filters as gm. Only fram I ever put On a vehicle

My oil change monitor goes off some where around 8,000 to 9,000 miles. My oil samples take into account that my truck does about 3,000 miles per oil change interval loaded and towing failry heavy. Going to KOH this year I grossed about 19,000lbs.

I think that old school wisdom is hard to over come with the modern fluid packages and engines. I am a big fan of the engine oil monitor systems in the vehicles and it seems that GM has a good program in the computer for that. It pushes the interval out a long ways and still seems to leave the oil plenty good for further use if needed.

Bottom line is that I think if you have a 2000 and newer vehicle and are changing the oil at 3,500 miles all you are doing is costing yourself money. 5,000 mile oil changes on gassers and maybe more on the diesels is good.

IF you own a ford Diesel good luck from what I know you could just run new oil all the time and still have injector issues. My dad claims his 7.3 starts to run rough at 5,500 miles on an oil change. Hydraulic injectors are dumb.
