If we go by what virgin oxidations show, Red Line followed by Amsoil SS have the highest values.  

 

There are so many esters its hard to know which ones they are using.  I've seen rumors suggesting Amsoil uses proprietary esters from Croda.  I have no way of proving so who knows.

@customboss could have some fun with that :) 

 

See that lack of a ragged top but two peaks (3,000 cm-1)? I have an idea but I'm not the FTIR master.

A comparison of Mobil 1 0w-40 oils.  Notice the 0w40 SP FS has an oxidation value of 8.7.  The others are upper 30's.  

 

Also, note the before and after shear stability (Viscosity @ 100C).  The ESP X3, C40 GT are more shear stable than FS 0w40 and Supercar 0w40.  However, three of them have some type of group v while the FS 0w40 does not.

 

The Mobil 1 0w40's with ester look like great oils.

Welcome! We’ve missed you. Thanks for sharing.

Guy had 117k on 17 V6 Colorado.  Started consuming oil between oil changes after running Mobil 1 and Pennzoil Platinum all its life.  Switched to Valvoline Restore and Protect and it stopped.  I can't speak on the Mobil 1 Triple Action as that is a new formulation, but some of the Extended Performance oils from the prior version didn't have the solvency to keep piston rings as clean as I would have expected.  Valvoline Restore continues to impress. 

 

Had this guy used Red Line, Amsoil SS, HPL, the piston rings would have arguably better in better shape.  I'm speculating of course.  HPL is touted as having the most solvency of any synthetic.  No idea if true.  It's loaded with a lot of additives though.

FWIW, HPL uses diester (adipate) and not POE.  

Explains the cleaning effect.  NEO was majority diester not sure they are still in business.

2024 Mitsubishi Mirage 1.2 liter triple

26,073 miles on unit

3,573 OCI (3,750 nominal target) Pulled sample early due to long lead times. :( 

Lab Oil Analyzers (AMSOIL) Thank you Nick for all you do for me. 

 

Red Line HP Euro Series 5W40 + 2 oz of Red Line ZDDP additive. Boosted to SH levels. 1200 ppm minimum. 

Dropped water temperature 10 F with Stant Superstat this OCI.

Had an event this OCI. Punctured radiator and temp spike. Seems this brew did it's job.  

 

Iron and aluminum only wear metals to show up and continuing to decline. Both under 1 ppm/K miles. Total just over 1 ppm.

 

Nitration and oxidation nil. 2 abs units over VOA

Viscosity at 1.3% shear. 

TBN, plenty left, 74% of VOA. Hovering 5 mg KOH/gr

Oil color is awesome. Still light amber

This oil is not stressed but I will hold this OCI length until wear bottoms out.  Still in data mode. 

 

Silicon is the only concern and until I can find a better filter, tis what it is. Doesn't seem to be bothering the power cylinder.  

 

This next OCI is the last of the original batch number.

2024 Mitsubishi Mirage G4 Sedan

1200 cc I-3 MPFI and CVT

 

30,000 miles

3,772 mile OCI

 

Service oil Red Line HP Euro Spec 5W40

Filter FRAM XG

Fuel Shell V Power Nitro + 93 E-5

 

Best part of the sample was  @Black02Silverado. First pass on this sample broke trends and created doubt. Contacted Nick and told him the issues I had. He listened patiently then advised me on my options and how to exercise them.  I contacted the lab. Explained my concerns and how I track results. Customer service saw the issue plainly. We had a nice discussion and then the ICP was rerun with a more believable result. People make mistakes. People find fixes for mistakes. There are NO perfect people nor perfect labs.

Seems we have bottomed out and leveled off. 

Next sample is scheduled for a 5,000 mile run.

 

 

Aluminum is the real winner in this grand experiment.

Mitigating skirt scuffing was the intent and seems to be the result.

Marked improvement over either 5W30 or 0W20.

Minimal improvement in Iron 5W40 V 5W30 but notable over 0W20

Total wear reduction is almost entirely the result of low Aluminum.

And yes, some minor contribution from bearing wear reduction.

    • Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆
    • I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death. 
    • In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them. 
    • I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.     
    • Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.
