Oil life meters

[tex78]

Changing your oil every 5,000kms is a waste in so many way's, thats only 3,100miles. Most all oil's non-synthetic are good for 5,000+miles, that's 8,000kms. Most recommendation's is 10,000kms on non-synthetic. Synthetic can go longer.
If your a long distance driver there is no need to replace the oil under 10,000kms, while short corner store driver's should do it more often.

U also have idle time in there.


This new energy conserving oil sucks mike. With out zddp ( Zink ect ) I have seen ohc chains stretch and 5.3, 6.0 , 6.2 , 3.6 ( in acadias ect ) with cams lobe tips gone ect. Like the Harding is coming off cause of lack of friction.

The new g.m oil is dexos and can see the difference from it to reg oil.

Zddp is a friction modifier that it for cams and chains. But they take it out for energy conservation.

Change regular mineral oil every 5000 km , and synthetic 7500 to 10000 km.

I do not believe in the 15000 - 25000 km oil that like amsoil says u can go that far.

I use gm oil and filters. Still have warranty on mine.

Shells Rotella T6 fully synthetic still runs a high level of Zinc. One of the last few to still have high levels of Zinc. Hence many with turbos run this oil and any breakdowns of engines running the Rotella T6 show very little wear and super clean engines. I base my oil changes on usage conditions, but with the T6 I feel very comfortable knowing I "could" go 10,000km easily.

Joe Gibbs oil has super high levels of Zinc and if you are willing to pay the price, should be a rock solid, long lasting lubricant.

What's a bit humorous to me is how oil has improved significantly over the years, and yet many people still use traditional guidelines for change intervals. Many are getting their oil tested (which is great feedback), and finding they can go much longer than anticipated.

Oil debates are always fun.

To get back to topic a little.........thought I was reading in the Ford Superduty manual that a person can modify the hour meter to coincide with specific Km intervals. I may be wrong....was a quick read.

Yes I know that a lot of the DSL oils still have zddp.

I was more refuring to the guys with gas jobs ect...

200 hours and it's oil and filter. So you idle lots in the winter what's the sense in going by km?? Worst thing for a Diesel engine is idle time. Get the oil smoking hot every time and boil out the condensation instead of idling from home to the grocery store you will have way less problems. My 08 duramax was almost dead on the 200 hour mark when the light came on. The oil life monitor is made out to some fancy monitor that sees how you drive and all that jazz I call bs. My dodge however I have no clue how it makes it's decision to turn the light on. It's all over the map.

 

[Thunderr]

Sold my 05 Dirtymax with 290,000 followed the DIC and it never burnt or leaked a drop of oil between changes. Used Rottella 15-40

 

[Highfly]

If the manufacturer says it's not time to change the oil, it's not time to change the oil IMO. I use the Oil Life Monitor 100% of the time. Had a 2000 GMC Sierra with the 4.8l engine (the little engine that could) and was not gentle with it asking a lot of that little engine. I put over 300,000 kms on it before I traded it in on a 2010. Never had a lick of issues with it. I do my own oil changes so save money doing it myself, I save even more by changing the oil only when it tells me to. I use regular oil not synthetics and jobber oil filters. 10 years, 300,000. That truck didn't owe me a cent.

 

[tex78]

But that was before all this energy conserving oil came out hifly ( where 90% of the oils is this now )

Plus the older roller cams don't seem to mind.

U tell me.

I have a 2011 6.0 chev gas pot with 145000 and the cam lobes gone ( Harding and all ).

We have been doing more and more cams and when u take them apart u can tell the oil they used.

I can tell you something interesting as i'm a little older then you Tex. Back in the day's 1980's...hahaha, loosing the cam lobes on a Chevy 350 was sooo common that most mechanics could replace the cam in the 350 in their sleeps.
Was the oil to blame or the manufacture of the motor????
Funny how the problem was actualy resolved with an updated cam. When a shop saw a vehicle with a 350 chev, truck or car with 35-45,000 miles on it, almost garranteed some cam lobes were going flat.
So the moral of that story is, it didn't realy matter how many oil changes you did on that motor, eventualy the cam was going to go flat.
BTW 45,000miles is around 76,000kms, way less then your 145,000km 6Litre chev, maybe them 6litre chev's have junk cams??? hahahaha.

 

[leadfoot33]

to add another thing if i owned one of the diesels with regen cycles and such i would definelty replace it more often, i dont like how hot the egts get and such.
mine im lucky, it doesnt tow hardly anything (sleds in the winter) just a daily driver, every 6 month it will get fuel filter, air filter and oil change with full synthetic.

 

[brian h]

brings back memories about the cam lobes on the gm in the 80's.use to be the rule of thumb for oil changes was for every litre of oil your engine held was 1000 kmh so a engine holding 5 litres of oil was 5000kmh between oil changes.the newer engines like the duramax hold 10 litres so that woild make it 10,000kmh for a oil change,my truck doing the oil changes this way the monitor says around 25% remaining on oil life.my truck gets a oil change every 10,000kmh and its a 07 duramax with 3000,000kmh with zero engine issues,does not burn oil.my blazer has 245,000 kmh on it and no engine problems

 

[medler]

Good info here guys !

 

[Slamnek]

I would usually change the oil between 6000-8000km when I had my 07 chev 1/2 ton and then a 10 gmc 6.0L using the dexos oil. The oil life meter would be around 50%. Both those trucks also had 11grease zerks and I'm sure if I let them go 12,000-16,000 km without grease I would have replaced a pile of ball joints.

I bought my wife a 2013 Equnox, motor lasted just over 2000 kms (yes that is not a typo). Just the way things work sometimes..... I didn't even get a chance to change the oil......
So are you telling me oil is now inferior because of energy conserving?? Got any data or links to back that claim up? I am interested, maybe i will change my theory. To me oil is oil. All must pass a certain standard.... now unless that standard has changed???

 

[crossfire879]

the gm oil life monitors are based on how you drive, rpm and time. the duramaxes will go around 15000 kms on normal driving and around 12000 kms pulling heavier loads and more idling.

i stick to the oil life monitors on my 2013's as there is an issue with fuel dilution in the oil, something to do with the regen system.

i run amsoil and filters in my 07 lbz's and i will go up to 25000 kms on a change

The new 2011+ duramaxes running urea dont have fuel dilution problems anymore. That was on the LMM (07.5-10) using raw diesel fuel in the dpf.

I'm sure its the oil.

It's cause there is so little zddp in the oil ( makes it have less viscosity so it restricts less ) that its not enough for parts that need it.

Either that or the cams are not made right.

But the roller lifters too are eating up.

Gm LS7 lifters are garbage. And that is the lifter gm uses in all the ls' s beyond of course the actual solenoid controlled active fuel management lifter. I have seen, run and even owned plenty of older ls engines that never have any issues regardless of oil used even with the newer oils. Spinning cam bearings is a different story.

Here is something i'll add to this thread. My last truck F-250 7.3Litre my son now own's. He currently has over 500,000miles....yes people not Kilometers. Its had regular oil changes every 10,000kms or 6,000miles. Never has it had synthetic in it, just plain old mineral 15-40. I bought the truck new in 1995, sold it to him in 04. I did all the maintinance on it.
My current F-350 6Litre has 270,000km, same deal, mineral oil every 10,000kms. NO issues and we all know how bad the 6Litre fords are.
BTW she's also chipped.

There are several articals regarding GMs OLM system, it is very affective and the warning actually has about a 25% error margin built in.....now like others I run Amsoil so the moitoring systems dont work, I've picked 20,000 or one year.....LOL as our bikes, summer car and boat dont but on enough miles they just cant changed once a year.....

Good information from IHR above......I've had 7 or 8 new trucks over the last 18 years....all GM's 5.3L, 6.0L & now 6.2L....I change oil on all of them based on the oil life monitor. I kept them till 150 -200, 000 km...and start over ......no issues in any of them.
I've kept one of my old trucks as a "beater"....creeping up on 300,000 km....no engine issues what so ever.....

I think those that say you gotta change at 3000 or 5000k are out of touch. Oil & engine technology has changed.

Even the farm industry is approving oil change intervals of 500 hours in their diesel engines..........compare that kind of hours to a truck....500 hours times average 30Km/h? = 15,000 km.....
