Your putting MMO (a VERY old additive that the maker proudly states never changed the make up of so its the same 60+ year old recipe) into new motor oil with countless money spent on research and chemistry.
So your putting a 1940's oil additive into your 2008 API SM oil.
It really just dilutes the OUTSTANDING chemistry of todays motor oil.
Yea, mmo will clean up some, but I would not make it a habbit.
TO each his own.
Yes I agree the oils of today are better than those 80 years ago. My only question to you is, if the oils of today as you say, are OUTSTANDING, why do the oils create varnish and deposits inside the engines even during regular scheduled OCIs?
That is a totally unbacked statement that is false.
There are COUNTLESS reports of running todays and yesterdays SL spec oil for 100,000s of miles and everything stayes squeaky clean.
My 04 lincoln has about 85,000 miles on it now. The insides are clean.
If you use a quality oil and a good OCI your engine will stay clean. It has been proven countless times by the users of Pennzoil, Mobil 1, AMSOIL, ect. . . .
Now if you neglect the car like 75% of the soccer moms and dads(who think oil changes are special treats for the car), perhaps the PCV valve goes, you wait to long on your OCI, you have a small coolant leak, ect. . . . , then you look and see you have varnish. You blame the oil.
unbacked and false huh? Well, a little about me. I use to have a mechanic’s shop and engine building center. I have built and rebuilt 100s if not thousands of engines before. About half passenger car/light truck and the rest high performance applications. I have seen engines gummed up from improper oil changes and I have seen some “cleaner” engines. I have also seen engines that were not gummed up but had a lot of varnish inside of them. Many of those customers had documented oil changes and proper maintenance schedules following the manufactures recommendations based on the driving conditions they were driving in. Most of the people that I dealt with that had a majority of the varnished engines drove in very hot, humid weather and had excessive idling from heavy traffic. There are also simple tests you can do to test for water/coolant leaks and nothing was wrong with those vehicles. So, for someone to say the statement I made before is not true and not backed, that person has never rebuilt engines as a professional before or have had any real experience dealing with engine work before.
Another example, my mother has a 1993 Nissan Pathfinder with 143K. I have changed the oil in her vehicle since the day she bought it new. I have either run 5w30 Valvoline dino or Castrol GTX 5w-30 with 3-4K OCIs. The engine in her vehicle does not have any gum so to speak, but it does have a large amount of varnish inside. Her vehicle was maliciously maintained the hole time because I did everything myself. I would have run MMO in it but she insisted nothing but “regular oil” was to be used. If I had run MMO with the oil, I believe there would be no varnish inside the engine.
