I wanted to know if Mobil 1 could clean as good as Pennzoil Ultra or PP so I asked Mobil. I essentially asked if Mobil 1 could clean varnish like PU and PP. They responded with
"Mobil1 is considered the highest detergent motor oil in the market place, it will prevent varnish, sludge and carbon build-up and also help clean vehicles that have a history of the issue as well."
So M1 has alot of detergents that are organic and non metallic? Good to know M1 has more detergents than its competitors who are known for cleanliness (PU and PP), right?

M1 is known for showing clean engines inside, at least from all the reading I've ever done on here.
I wouldn't make claims that M1 is better or not than Penz oils, but as one who has probably used more M1 oils than most anyone here at BITOG over the years in many differant kinds of engines, I can say M1 keeps engines remarkably clean for the life of the vehicle.
Asking XOM how good the detergency is of their flagship product provided the predictable answer.
I would guess that most of the better formulated synthetic labeled oils are pretty equivalent in their properties grade to grade, including M1, PP, PU and QSUD.
Hi,
tig1 - I can concur. I have used Delavc and Mobil products since around 1955 - commencing with Mobiloil Special 10w-30.
I was a late user of Mobil 1 products in my own cars - only since the mid 1990s
In various tests in diesel and petrol engines these products have always produced remarkably clean engines in a wide range of applications - and over many milliosn of Kms
I have tested a number of Brands for a number pf organisations over many many years. The Mobil and Delvac products were alwats top of the tree for cleanliness when used as specified
It is unwise to expect any lubricant to "clean up" a heavily varnished or sludge laden engeine. Sometimes there can be a slight improvement. In many cases these engines are the product of poor design or maintenance and/or by using non recommended (specification) products
ShellAero, not Mobil or any other lubricant manufacturer, kept the engines clean and running perfectly on the cold war era planes I flew. However, each engine consumed 20-30 gallons of oil from an 80 gallon dry sump on each flight of 12-14 hours.
Perhaps a Mobil product could have improved on that consumption rate.
ive used mobil 1 and pennzoil yellow bottle quite a bit in the past and both of them did a great job of cleaning and keeping my engines clean. i have not used pp or pu in my personal vehicles. i do change oil for a guy who runs pp and pu in his vehicles at 10k mile intervals and his engines are clean when looking through the fill holes. i think almost all modern oils will keep engines clean if the oil is changed when it should be.
the question is what oil is bad???
These days oil is oil and the cheapest oil with api sn and ilsac GF-5 is just as good as the rest with those ratings..
Believe me if one oil was the best that oil company would advertise that they are the best.
I read an on article on PIQA website about some oils convience stores where selling. Some of the oils they found where 1930's oil with a SA rating. Now that is bad oil.

This oil i don't believ had that SA rating, but PIQA issued a warning statement about it.

How much of that oil was burned, and how much of it leaked?
Were these Pratts or Wrights?
Just curious.
