Mobil 1 10W-30 TriSynthetic on Toyota

[BOBISTHEOILGUY]

I moved this from another post as it is a new oil analysis report which deserves it's own thread.

Looks pretty darn good to me. Exceptionally low wear numbers for 4000 miles. Granted highway.

 

[Patman]

I hope the new Mobil 1 holds up as well on the wear numbers too! I wait patiently for someone out there to have results on the new stuff, but I do realize it's too soon yet, since it's only been out such a short time.

 

[richard612]

Hey, isn't this the 1MZ sludge-maker? This particular example has a motor-melter bolted on top, too!

Good numbers, considering...

 

[BOBISTHEOILGUY]

yeah, not bad numbers but it too was on it's way out just like a lot of other oils used in the toyota's.

Had he adhered to the recommended toyota 5-7500 mile drain interval, by 4,000 miles it would have been a 20wt as it was right inbetween the 20 and 30wt in 3000 miles.

As long as he maintains the 3k interval he will not have a problem.

 

[Patman]

It looks to me like the viscosity did not change, as Mobil 1's specs for new 10w30 tri synthetic show a 10.0cst at 100C.

Why would 10w30 synthetic change viscosity so quickly anyways, doesn't it have no (or extremely little) VI improvers in it? I know M1 10w30 used to advertise that it had no VI improvers in the past (with it's Advanced Formula)

 

[BOBISTHEOILGUY]

Good point Patman, I haven't looked at their base oils cst's so if it started out that way then I stand corrected.

 

[Patman]

This also proves what I've been telling people in the past, that the 10w30 Mobil 1 will hold it's viscosity, but the 5w30 Mobil 1 will thin out. I have an oil analysis report that someone has on their 4th gen f-body which shows M1 5w30 shearing back to a 20wt after only 2300 miles. I'll have to dig up that report when I get home.

 

[Patman]

I found a copy of that oil analysis here in my email box at work actually. He doesn't say what his car is, but because it was from the 4th gen f-body list, it's going to be either an LT1 Camaro/Firebird or an LS1 Camaro/Firebird. Here it is below:

richard612 Yes this is a 1MZ-FE sludge monster, though I haven't had any issues in that area. The motor melter AKA a roots type blower also tends to make the front tires melt as well!

bob This was the first time that I ever exceeded a 3,000 mile drain, since most of the miles were accumulated in about two weeks. I switched to a synthetic prior to the blower install due to concerns about heat [pump a lot of air and you'll get lots of heat]. Do you have a recommendation for something to try in your product line? I only have enough TriSynthetic Mobil 1 left for one more oil change.

Here's Terry Dyson's interpretation of the above analysis. In response to the air filter question, it is an OEM Toyota paper filter. Terry's service was fabulous with same day response.

1999 Toyota Camry LE V6 [w/ Eaton M-62 Supercharger @ 4psi]

Lube Type Mobil 1 Tri-Syn
Grade 10W-30
Oil Filter OEM Toyota

Total Miles 26,737
Lube Miles 3,999
Sample Date 05/23/02
Make Up Oil 1/2 QT

Iron 2 Excellent, lower than most I see on the Toyota engine. Lowest I have ever seen is 5ppm.

Chromium 0 Normal.

Nickel 0 Normal.

Aluminum 1 Normal.

Copper 1 Normal, low.

Lead 2 Normal.

Tin 0 Normal, low.

Cadmium 0 NA

Silver 0 Normal.

Titanium 0 NA

Vanadium 0 NA

Silicon 15 Normal to low. What brand/type air filter are you using? It's working well. Lowest I've seen is 10ppm.

Sodium 9 Normal.

Potassium 2 Normal but usually 0. Oil rag used to wipe dipstick may have had some residual coolant on it.

Molybdenum 0 Normal, unless oil uses it as an additive.

Antimony 0 Normal, can be an additive.

Manganese 0 Normal, usually 1 ppm.

Lithium 0 NA

Boron 73 M1 signature add, normal.

Magnesium 1,739 M1 signature add, normal.

Calcium 946 M1 signature add, normal.

Barium 0 NA

Phosphorous 755 M1 signature add, normal.

Zinc 887 M1 signature add, normal.

Fuel [% Vol.] 0.5 Normal.

Soot [% Vol.]
Water [% Vol.]
Viscosity [100 C CS] 10.0 Right on 30 w and what the oil begins at.

TBN 6.73 Starts about 11 or so, being used to reduce wear. To keep your engine pristine I would have changed based on this.

Overall solidly excellent report.

2533A, another good set of M1 figures. As was just posted by icruse re the inferior Noack volatility of M1 0W30 TS versus Amsoil 0W30 the M1 performed better. Seems specs don't tell all.

 

[2533a]

Sprintman,

The Mobil 1 Tri-Syn is performing well in this engine. it's a pity that I only have enough stockpiled for one more oil change. After that I will have to start all over again in finding a good oil.

Or make a trip up to Canada. There are stores and stores filled with SJ and SL formula TriSynthetic up here still. There is no SuperSyn here as of yet.

 

[2533a]

Patman,

What is Mobil 1 running per liter up your way and is there GST on motor oil? Then there would probably be a cut at the border for Dubya, but with the exhange rate it might work out. Actually we've talked about going to Granby Zoo and Magog, PQ is on the way so I could shop for M1 there. My wife already thinks I'm nutty about car maintenance, so she'd probably just sigh and tell me to go ahead!

[Patman]

Most Walmarts sell Mobil 1 for $6.35 per liter plus the 15% PST and GST in Ontario, but you can find a few places that still have the 5L jugs which are $25.40 per jug. That's the best deal of all, I bought a few of those up last year.

I'm not sure what they would charge in Quebec though, I think their PST is at a different rate than Ontario.

Don't write off M1 SuperSyn, it may surprise us. I think GeorgeCLS said he has seen many analysis reports on SS v TS and I think he said no discernible differences in the wear numbers. Could be wrong though.

 

[GeorgeCLS]

Confirming Sprintman's comments, yes, I review the oil analysis results for several fleets running Mobil 1 in both small delivery trucks and saleperson's vehicles. Both see city driving conditions, stop and go, MUCH idling, different drivers, etc. in other words some pretty difficult operational conditions. All vehicles are very well maintained, however, with excellent PM. Some of the vehicles have now seen all three iterations of Mobil 1, from the original to Tri-syn to Super Syn and graphing the results indicates just about as straight a line as one can have. Frankly, I see no discernable difference in all the parameters reported in spectrographic analysis. Some units have well over 200,000 miles on the engines and 30,000+ miles with the Super Syn formulation.

Georgeseq,

So why the change to the new formulation? Have you seen no difference in TBN retention, for example, or a reduction in shearing over time?

TooSlick

 

[GeorgeCLS]

Operationally I have never seen shear take place in these applications with Mobil 1; it is extremely shear stable. We had one company where the night vehicle lube person was doing Parker P51 oil changes (not changing oil, only filter) and one vehicle in particular had very probably 80,000 miles on the Mobil 1 10W-30 and was still in grade..
Mobil's reason for reformulation was for performance upgrade. As I shared in previous posts, the "sypersyn" formulation is for real, having been developed years ago, sat on a shelf gathering dust until one of the assigned racing lube engineer's ran into a bearing life/film strength problem. ie. bearings were failing in the race engine and the engine builders were blaming Mobil 1. He had a batch made up with this particular molecule blend and the problem not only went away but the weak component lived better than the previous strong design. So, by fluke rather than design, the supersyn (don't know where they get those names) was formulation is an evolutionary improvement in Mobil 1's performance. Mobil 1 and Delvac 1 are Mobil's flagship and they are going to do everything possible to keep them one generation ahead of the other major synthetics such as the Castrol/Valvoline/Quaker States of the world..

The same is true for Amsoil, which is constantly upgrading its formulations to meet the ever increasing demands of service, competition, etc..
