Overkill,

I believe in science and facts but also using common sense and not overlooking the obvious. I tried calling my mechanic but they are closed for the weekend so I will call him during the week and post his answer whether it agrees with you or me.

Have a great weekend.

Toto.

I'll counter your question with a question:

What is the purpose of going from a high quality to synthetic to a "high mileage" oil?

Please note that there is no "high mileage" version of Delvac 1, M1 0w40.....etc.

OK. Here is a picture of a oil pressure sensor or sending unit(same thing). Notice on the left side of the sensor the tapered threads. This screws into the engine at a place where there is typical oil pressure of the engine. Now, the leaks don't occure at the threads but through the sensor itself and oil comes out of the unit, at times by the buckets(so to speak). I had two sensors fail 40-50 years ago before M1 oils were even on the market. What makes these unites fail and leak is the constant pressure and or vibration of the engine. Here is the link.

I would say the trans would still be working if I have used Chrysler Mopar ATF rather than redline.


Redline ATF has protected my Ford trans just fine.

I'd trust tig1 on this one. He's a bit of an expert in the matter, and I'm not talking about M1, either.

I don't know why people hate me so much. If I already knew the answer, I would not have asked the question in the first place. LeakySeals says moving from Mobil 1 5w-30 to Mobil 1 high mileage 5w-30 was a "terrible" move. I just would like to know "why?"

Uh huh. Well I only blame myself. Redline has NO builder approvals of any kind, so who knows if it's any good. Like Amway products it could just be all "multilevel marketing" and no substance. I should have known better and stuck with Chrysler's ATF+4 oil.
 
This thread seems to have runs its course, but what the [censored]...

I started using full synthetic 5W30, mostly M1, in my old Ranger at around 70K miles. I sold it at 93K miles and it did not leak a drop of oil. You could eat off the oil pan on that truck. It was spotless. I have honestly never seen an oil pan that looked cleaner at 93K miles.

I started using full synthetic 5W20, almost exclusively M1, since 85K miles in my current Ranger. It does leak oil, but it is the same amount it has leaked since somewhere around 30-40K miles. Vulcans leak oil; when they don't, you're out.

In both cases, synthetic did not really contribute to leakage. Either the engine leaked or it didn't, and M1 made no difference.

It has nothing to do with hating you, calm down!

If somebody has observed good performance over an extended period of time with a given lubricant, what sort of benefit do they wish to gain by changing to a "high mileage" oil that will lack many of the approvals of the oil they are replacing?

I see the high mileage oils as a bit of a gimmick. And while they may work to expedite the cleaning process for somebody who used "Phil's Home Garage lube in a bucket" oil for the duration of the car's existence, an engine that has had its entire life or a good portion of its life on a quality synthetic lubricant should have no need for such products. Heck, an engine that has spent its life on a quality lubricant changed at an appropriate interval, be it synthetic or not should have no need for this type of product.

dslofti,

In my last 5 years I had my moms car to drive I put in Mobil 1 and it did the same thing as you described. I just figured it was the oil cleaning all the internals.

And as far as I can tell Mobil 1 High Mileage is every bit as good as the straight M1 or M1 AFE. It carries all the same API and ACEA ratings as its parent. Perhaps you're right there's no reason to quit M1, but if your engine does start leaking oil, hy not give the M1 HM a try?

Glad you asked!

I've been wrenching on engines since I was around 10 years old. My grandfather owned a fleet of antique boats, which I worked on regularly, and when I got older I began working on cars as a hobby.

I've torn down many engines, and have posted pictures of my build-ups on this board.

I come from a strong engineering background and have a great deal of mechanical experience with pretty much everything automotive.

And your reading comprehension is astounding! I never once said you weren't allowed to post on this forum. I asked you to read more and post less. Obviously that went in one ear and right out the other.

My assessment of your qualifications is reinforced every time you post.

My intellectual contribution to this board is already recognized by my peers on this site. Do you honestly think that your attempt at criticism here is going to work to humble me in some way?

I have a 208,000 mile Ford 4R70W that behaves like the day it left the dealer lot. The last ~90,000 miles have been on D4, why am I having zero issues? This 4R70W is about to the swapped to "multilevel marketing" Amsoil ATF and it's finally getting a external transmission cooler, want to bet it never has a fluid related failure with Amsoil fluid either?

I guess the real question is what failed in your Chrysler trans and what leads you to believe it was fluid related, you know, other than coincidental timing?

Fantastic advice for blackman777 (or anyone else who racks up 300 posts in less than their first 30 days on this board).

And sunkship.
Overkill gets post of the day with the one above. I enjoyed reading that.

I see this a lot on this forum but don't understand it. Why swap fluids if the one you're already-using (Redline D4) is working so fantastically. I always pick on fluid and then stick with it. "If it ain't broke, don't fix it." That's why I'm wasting so much time researching VW oil. I will pick the best one for my new beetle, and then run it for the next 300,000 miles without alteration.

As for the Redline C+, when I went to the allpar forums and told them I had used it, they immediately said that was a gigantic mistake. When I said the seals started leaking, they said that's what happens to every person that uses a non-Moper ATF. Switching back to Chryslers +4 fluid fixed the problem, but did not undo the damage to the torque converter (which my dealer said needs replaced). So the car was basically went from perfect running to undriveable thanks to my little Redline C+ experiment.

Overkill demanded to know why I (factory mechanic) would not work on his own car. Overkill said it is suspicious and he suspects I'm lying about being a mechanic. How about? Because I don't WANT to work on my dumb car... I want to enjoy my Saturday & Sunday off... not sweating under some greasy machine. Besides I don't own any of the proper tools for working on a car, and don't waste to spend thousands of dollars buying them. ANYWAY: The accusations are uncalled for.
