He said the detergents were TOO HIGH and would lead to spark plug fouling and certain types of corrosion over a long term. Redline also said the same thing regarding their diesel oils. I kept telling the tech at Mobil, "I know you guys are very strict w/ warranties and all, but if I am out of warranty, theoretically is this a good oil to use in my car". "No, definitely not"!

I don't think Doug the Honorary Elf will agree with this...calling Doug Hillary....Doug Hillary do you read me?

PS The only way this makes sense to me, beyond the fact that a diesel has no spark plugs and so can't have them foul, is if the process of countering diesel "resdiue" reduces the aspects of the detergent package that cause the effects the Tech said. Otherwise it does not make sense.
 
Hi,
Elfmeister - I hear you.....

I would NEVER use a very low or very high ash high TBN "diesel engine only" oil in any petrol engine. Well, unless there was no alternative and then only for a short period or a critical need top-up!!

I have used mixed fleet HDEOs (from Castrol, Shell, Mobil and Caltex-Chevron) for decades (sinec the 1950s) in petrol engines WITHOUT ANY DETRIMENTAL EFFECTS WHATSOEVER

IMHO Losiho gives the correct advice above. The Mobil Tech should be "trained" - or re-trained!!!

I had "an experience" with a local Mobil Tech two days ago that still has the hair on my back standing upright! He rang back later to apologise and say that he was wrong and sorry. It does make you wonder!!!!

These types of comments are the source of mis-information and misconceptions! We have one "ex Amsoil" person who still continues on along this path on this Board!

KISS is the best policy - sadly it sometimes the facts get lost in the rhetoric

I'll give him credit for at least calling back, admitting he was wrong, and apologizing. How many times do we see that happen in today's world?

But, you're right, it does make me wonder! Did using the T&SUV in my '02 Saab 9-3 somehow cause the manual tranny seals to go bad at 39k?

I have used Delo 400 as well as Delvac Super in gasoline engines with fantastic results, no plug fouling whatsoever, it is probably marketing constraints that made the tech guy give out that explanation.
 
IMHO, the difference is due to the fact that the T&SUV has a higher viscosity and cannot be labelled "energy conserving". The manufacturers have to specify ecng to claim the increased mileage for their cafe numbers, so they cannot allow anyone to recommend thicker oils in their engines.
 
As I recall the LAPD uses evil 15W40 HDEO in their Ford sedans, typically Crown Vics I guess, when they should be using some sort of 20W PCMO. The HDEOs that I use for the diesel in the truck all have dual ratings, the last jug of Delvac 1300 15W40 labled CI-4+ and SL/SJ, and Mobil 1 T&S labled CI-4 and SL/SJ. The label for T&S states 'Outstanding protection for gasoline powered trucks and SUVs', which seems to be undisputed.
 
The sulphated ash level of the CI-4+ rated, Delvac 1 is about 1.35%. That's below the 1.5% limit for ACEA A3 and the 1.6% limit for ACEA B4.

Levels of ZDDP are somewhat higher than API SM specifications (P of 1075 ppm/Zn of 1200 ppm), but not enough to be an issue. Unless there is something about the specific types of organo-metallic detergents they are using, which seems far fetched.

Pablo - Doug must be talking about YOU - I recommend D1 all the time.)
 
Hi,
Oh Pablo please do not infer that I dragged "...Amsoil into EM incompetence"

The facts are that there are many people giving advice on lubricants that is rich in mis-information and laced with incompetence

The sad thing is that many people in a position to advise others (such as the Mobil Tech(s))spread the mis-information thicker than most.
Training and exposure would help immensely

It is not only Mobil but I have found the same with Castrol and others - especially with the "HELP" 1 800 lines.
I am sure that Amsoil is no different than the rest Pablo - Goggle told me so!

As for mis-information, just look at the BS about "excessive valve train wear" and "excessive shearing" with 0w-40 synthetic lubricants peddled by some on here!

As a Customer and as a result of my recent experience I have asked the heirachy of EM lubricants Division here to consider more basic up front training for their people who are in direct contact with the public

No BS Pablo - just the facts!

Regards

Just name the name....don't drag Amsoil into EM incompetence.
 
Good deflection Doug. But your "facts" are again 100% slanted to defend EM. Fail to see why you only mention Amsoil when the Wal-Mart Castrol Technical reps, Shucks/Kragen/AZ Oil PHD's, and K-Mart Shell Sales Engineers are fully degreed, proficient and chock full 'o knowledge...just waiting for the Dougster to use as examples.....

You fail to mention the Amsoil T-1 certification, the Amsoil technical training classes, videos etc. While I'm the first to agree there are a lot of Amsoil dealers who are hacks, former Amsoil site guy, TS, is not one of them. TS uses some wild examples/analogies sometimes - however he is not full of shrimp on the barbie as is directly implied by Doug, I swear I don't sell Mobil, Hillary.

Oh yeah check out my 5W-40 UOA.

The Mobil 1, 0w-40 consistently shows significantly higher valvetrain wear (Fe) than other competitively priced synthetics, including , Redline, Delvac 1, Royal Purple and the GC/0w-30. It consistently shears down by 10%-12% after 5000 miles of use in the VW/Audi, SAAB or Subaru turbo engines. It shows NO advantage over the very shear stable, Mobil 1, 10w-30 in any application I've seen to date - either in terms of wear protection or TBN retention.

There is no test data in any of the SAE, "Fuels & Lubricants" papers published in the past seven years that shows the 0w-40 outperforms the Mobil 1, 5w-30 or 10w-30 - except in terms of "staying in grade". Since this "stay in grade" performance is achieved by shearing significantly and then thickening back up due to oxidation/evaporation, I don't see that it offers any tangible benefits to the end user.

These are facts which are clearly and consistently supported by the past three years worth of UOA data on this site - they are NOT opinions....
Any experienced engineer who looked at this same data would come to the same conclusions....
