Mobil 1 0w30 (2003)

[buster]

I thought this was interesting. 20 years ago old and the formulation looks almost identical to what we see today. Some differences include ZDP, and lower Ca that is now balanced with Mg. I'm sure there are other differences too not visible.

This is probably what the guy from Lubrication Explained meant by stagnant formulations.

Moly/Boron are clearly time tested and proven.

That’s a whole lot of Ca!

 

[fantastic]

Looks to line up close to ESP 0w-30 w/slightly less phosp. & zinc.

We are no where near that TBN today and the price is what 70% higher?

Any idea if this was the tail end of the tri-syn era? I loved the tri-syn. Absolutely some of the cleanest engines I’ve seen at high mileage.

I think this was SuperSyn, so post Tri-Syn.

I started using M1 5-20 in 1978 and paid $5 a qt then. No where near 70% increase today.

Unless you’re really swimming in blow by there’s little need for high TBN today. Back then there was a lot more sulfur in fuel.

As Buster correctly stated this was after the 'Tri-Syn' version and the beginning of the 'SuperSyn version'. I used this oil often in my 02' Buick and 08' Corolla. I actually still have a some of it. I also have some Tri-Syn in my 'collection'.

Quality oils in the old days had much higher TBNs than today because fuel contained more sulfur back then. With fuel now having lower sulfur, there is less acid products to neutralize.

This is supersyn. Tri syn looks more like HPL PCMO except with alota moly that tri syn didnt have

Actually...the SJ version of Tri-Syn didn't have moly but the SL version did.

I know that AN's were one of the 'three' parts of 'Tri-Syn' which probably accounts for the engine cleanliness
that Glenda W. mentioned.

Correct.

True if you buy it at Walmart it is only .569476%

What did it cost throughout the 80s and 90s? Also when did it start coming in gallons or 5 quart jugs?

What about running E85 or even our current E10 fuels? From what I understand, ethanol creates more acids than pure gas. Is there any negative to higher TBN?

API SL in 2003. Where did this VOA come from? Was it done back in the day or was it done recently from an old container?

I went back and found it on here.

As I mentioned earlier I used a good amount of this oil years ago and liked it. I got it on 'Clearance' for $3 a quart IIRC at RS Strauss (a northeast chain that has since gone out of business). I'm assuming it was PAO based because I don't think EM had started using Gr. III yet.

Another oil that I bought a good amount of on 'Clearance' at AA around 2007 was full synthetic SM rated Motorcraft 5w20 (not the semi-synthetic). I liked the way it ran in my 2001 Accord that spec'd 5w20. That was back when I was afraid to go over 5K on an OCI but in hindsight I'm sure the Motorcraft FS could have went much further. The base oil was made in Korea.

Sadly, with the 'advancement' of DI I'm back to doing shorter OCIs.

In the 80s-90s the cost was around 5-6 bucks a qt. I've been buying M1 by the jug around 20-25 years.
