Synthetic Oil

Iv been there too.

We all should get on board air of some kind really. If its a cheap pump that is cordless battery powered or if its a nice setup from Viair.

And Dont forget to drop the spare a spray some grease or fluid film on the cable. They get rusted and stuck easy.

I have a viair that I keep in the truck. It comes in handy. I think it's the 450.

Airing the 35s up on my PW from like 30 to 50 psi usually takes like 3 minutes

So what exactly lowers TBN? Heat cycles? Overall heat exposure?

It can't be fuel dilution because there's virtually no trace in that UOA...

Combustion byproducts is what I was told.

TAN kills TBN.

We know that.

TAN is acid levels

The article above explains it well

Nah, some guys like cookies some ice cream, kyles truck happens to like tbn.

0-3% humidity, all the time!

there is some benefits to living on the left coast, although few and far between they may be.

This correlates to what I was told way back in my John Deere days during training on their engine oils.

I wouldn’t life that far to the West, y’all crazy out there! Southwest is a good spot, plenty of mountains and lakes and 4 real seasons.

And no humidity

Ok, "back in the day" (yet again) - in Mobil Industrial Lubrication Engineering, our put on TBN (total base number) was acid formation from high sulfur diesel fuel was the culprit.

In fact, the Mobil Marine Guys supplied Mobilguard Engine Oil with a TBN of 70 to ocean freighters because they burned Bunker C slop chocked full of sulfur, among other crude oil contaminants. These crosshead engines didn't even get oil changes - they burned the engine oil! They'd pull into port and they'd fill the lube reservoir. Those were the days without any engine emissions controls on marine vessels. The ISO is going after them now.

Ok, so what forms acids in an engine crankcase? Fuels with high sulfur, of course, but what else? Sheared down additives is a likely suspect, yes?

Or tornadoes, earthquakes, or blizzards. Just blast furnace heat.

In my case.

Using lots of redline S1[emoji16]

Ok - so are we seeing higher TBN depletion from Red Line than other oils? Makes no sense to me - polyol esters are inherently much higher resistant to oxidation than other base oils. Does this mean the engine is out of tune and putting too many partially-combusted contaminants into the crankcase?

 

[HEMIMANN]

We should be seeing the same TBN depletion rates from the same engines with Blackstone reports of high TBN depletion rates.

If these rates vary by engine, then some engines are likely out of tune, and/or fuel supply quality issue (higher sulfur gasolines in that region).

I these rates vary by oil, then there's likely an additive problem with sheardown.

I mean S1 the FUEL additive

The oil itself has proven time and time again to hold way higher tbn for 8,000 plus miles than my truck.

Its my fault. I need to cut back. It was an experiment.

So the cheap ******* in me is making me want to switch from schaeffers despite being completely satisfied with its performance. I have 2 ideas on what to try

my first is m1 euro fs 0w40 since its viscosity is nearly the same as redline 5w30 but its only 50 bucks for a 12 quart box. Also its add pack is phenomonal and the base oils are great as well. 30 percent pao and 70 percent gtl according to the msds. A pour point of -76 is ideal for me as well

my second idea is a mix of 2 oils. I have always used mobil 1 except for this truck. Mobil 1 ep 0w20 has a great base oil thats 60-70 percent pao with a pour point of -65. I also came across a voa for mobil 1 racing 0w30 and its ad pack is insane! 1700ppm of moly 3000ppm of calcium and 2200 ppm of zinc and i think 2000 ppm of phosphorus. Tbn of 9.9 as well and 70-80 percent pao base as well. My thought was maybe run 1/2. Quart of m1 0w30 with 0w20 ep. results would be a great ad pack with a majority pao oil and id assume some esters from the race oil and the 0w30 should increase the viscosity a little bit maybe but i have no idea how much since ive never mixed oils and i dont think the 1/2 quart would do much to a 0w20

ill likely just use m1 fs 0w40 but the second one was just an idea i had while i was supposed to be working today

I use much si-1 with my 5w30 redline and my tbn retention is what I call exceptional. Something else is at play.

 

[LeesEvoX]

This is another oil i might try at some point, and actually mentions the 6.4l HEMI engines.

I used this oil for break in on my 500WHP Evo to get everything seated, and cosy. and was also used by the owner for their shop GTR, and Subaru WRX.

If the add pack is similar to the 5w20 then its a phenomonal oil

What is si-1 again? A fuel or oil additive?

 

[Burla]

Fuel, but there was a post on BITOG and thickening of oil with PEA additives, which of course si-1 is.
