I wonder why they are not showing TBN or Nitration?  If TBN was 0 they would have flagged it.

You and I have different points of reference when it comes to TBN. I expect you change at 1? I change at 50% of initial when starting point is done by the same method. NEW number is normally about 2 point higher than UOA numbers. Blenders use a different titration. So I reference the blender, take two points off and change at 50% of that adjusted number. I don't change to get maximum oil life. I change to get maximum motor life.

I understand.  I'm just wondering why they didn't post the TBN or TAN.

If I were to venture a guess? He's had multiple changes at roughly the same intervals. After a few where they did report I would guess they are comfortable that for the same operator and fluid and OCI the result will be most likely the same.

Oil Analyzers is pretty good.  Not like them to leave off information, especially information that you paid for.  Just doesn't seem right to me.  Even if it is the same, it needs to be in the report.

I agree! It's hard to even pay people to do their job and expect it gets done.

Given the amount of fuel burnt the normal 8 ounces in 2500 miles is not quite two ounces higher than the calculated maximum so the motor is already 'hurt' and we know why. Rings sticking. It's just a Ecotec I4 issue. And we know that the harder you lean on a motor the more oil it will use. Even a healthy one. So....what I've asked the wife to do is bit the bullet and hold her speed down to a maximum of 62 mph. 

 

If it goes back to 8 ounces, fine. Tis what it is. IF it gets worse then we can try another 'ring soak' which brought it back last time or just replace the motor. Jasper. A heathy motor that burnt 97 gallons of fuel should land between 0.03% or 3.7 ounces on the low side to 0.05% or 6.2 ounces at worst. 

 

There is over a 20% difference in fuel economy between 60 and 75 in this truck. Allot of load. I guess we'll see. If it will get better and if she will cooperate.

143,300 Mile Services

 

7/8/2021

Sugar Bears:

2015 Terrain SLE-2

Ecotec 2.4 I4 

143,300 miles actual (Ending a 1,500 mile S7 cleaning cycle at 5:1) 

3,300 miles this OCI

No measurable usage this OCI. The TRIAX S7 did what it was advertised to do. Clean. 

 

4.84 quarts of COSTCO Kirkland 5W30

5 Ounces of TRIAX S7 (31:1 mix ratio)

1 Purolator PL15436 filter

 

This next change will be shorted to get back on even OCI's at 145,000 and the mix ratio will richen to roughly 10:1 and remain like this until I work off these cases of Kirkland or the rings give up again. 

 

Now will it stay clean? 

:dunno:

      Oil Consumption

      This is the 6.6 gasser section of the forum, you should either delete or modify your previous post as it is misleading for anyone looking for factual information on their 6.6 gas engine.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Well....I've done my first intake gasket. Probably wrong, but...we'll see?   Ultra black on the china walls and 1/4" up onto the sides of the intake gaskets. Permatex High Tack (couldn't find Gaskachinch) on the head side of the intake gasket. I read wrong and it says you're supposed to put it on the mating surface of the head, not the gasket. Hoping it's like a PB&J sandwich where it doesn't matter what side the PB goes on so long as there's jelly. That crap is messy/sticky and I got a dab or two on the intake port openings, tried to wipe it off. Hopefully it won't be a big deal and will only aid in sealing.   Per instructions I left the intake (top side) of the gasket dry except for a light smear of RTV around the coolant ports. Wiggling the intake in there was a bear but I had help to free me of surrounding wiring/stuff but I was basically able to set it straight down lined up with the bolt holes.   I did not think to wait until the RTV skinned over but there probably was 5-10 minutes while it sat before installing the intake.   Bolts finger tight first. Then, followed the Chilton's manual pattern to snug them to 15 lb-ft.   Waited a little over an hour, and then did the final torque in sequence again to 35 lb-ft.   Yesterday I replaced the fuel pressure regulator and got my new "nut and bolt kit" (fuel lines) installed. Damn GM used security torx on the spider, which I don't have, so I got scammed at the local HW store for an off-brand security Torx bit set.   The new driver's door mirror arrived yesterday, so, there's a chance this thing could be running and road legal tomorrow? I don't want to get my hopes up.   This will be my first time stabbing a distributor, too. Although, lucky me, someone else marked the old distributor for removal previously, I did see that. (Someone's been here before!!). Engine is still at TDC so it *should* be just a matter of transferring the mark to the new dizzy and rotating it into place.

      He has his dad’s newer truck he’s put away. He has several old cars he rotates between him and his family. I’ve seen a restored square body and a SS Chevy truck he’s sometimes drives. He did raffle off a new suburban recently. As much as he is watched if he drove new stuff as a rule we’d know it. It would be fine by me. I don’t care what people prefer. I got one more new one in me. I’d rather my wife get one. I can’t get her out of the Genesis. Don’t tell anyone. I want her to get an electric truck. I want to put a generator in the back. Just because. She hasn’t bit yet.

      Yes, you must have seen my thread on the Blazer. HOT GARBAGE, but I love them anyway. I'm convinced every car guy has a soft sport for an S/T series somewheres. Probably even a Panther too, if I'm being an honest car guy. That doesn't mean they aren't junk. And they definitely don't get better with age. I sometimes play with old cars, but that's by choice. I don't rely on them and they aren't my everyday fleet.   Derek plays the common man on Youtube and that's no doubt where he started. Now he has Youtube money (and Motortrend, etc). You think his crews and his wife ride around in old beaters when they're chasing him and his wrecks across the country? No he's got newer and nicer stuff for that, you'll see glimpses of it in the footage.

      You refuse to own anything made in this century yet you reportedly own... a 2007 Silverado, which is now almost 20 years old. The dissonance.... turn up your hearing aid?   You clearly don't understand the government contracting process, brother. We send people to die on front lines, keep the public safe, and make people's husbands, wives, children enter burning buildings with equipment from .....wait for it.....   ...the lowest bidder....   Just because something is used for a long time doesn't mean it's good. But it might be cheap and plentiful.   Please, continue to whine about new trucks in a thread dedicated to new trucks, which you've said you'll never own. We get it. Go tell everyone how you're stuck in time on a Panther forum. I mean, Jesus, an 86 isn't even one of the good Panthers.
