I think TC-W3 would be better?
Nope! I just 2 weeks ago,had my tank dropped,and spark plugs replaced.been using tcw3 ,valvoline,from napa. 1oz per 5 gallons.have 18 gallon tank.waited till fill needle was quarter mostly. Some tanks I did 1 1/2 oz,making 6 odd per tank.like 3-4 timed.15 tanks on 4 odd tcw3.Halloween night,car sputtered n turned off.numerous times. Towed. Mechanic gas station said their was some kinda oil in tank.spark plugs fouled n oiled.up. $550 job. Do not use tcw3 oil in gas..maybe diesel,yeah.

As for MMO..it does work.I like it.but my 98 less bee threw p0420 codes.catalyst inneficient.bank 1 sensor 1.upper 02 sensor.CEO would go after like every 400 miles.stopped using mmo,code never came back.same on my 98 corolla.
It's use it as a 500 mile engine flush maybe.as much as I want too use mmo,it is getting through combustion process,and onto 02 sensor and into CAT.
I can only stay with Lucas ucl.never threw any codes.

I did gain mileage with tcw3 though! Without it, I could go 190 miles.with tcw3, 253 miles.it did work! But over time it accumulated too much in tank.running too ,quarter a yank,better too have run it just touching empty.that about 24-30 miles for me. But it coated the spark plugs. I would pump 7.2 gallons,take.pump out,pour 4 odd tcw3 in,then fill gas too 12.3-13.7 gallons..so it would mix better in tank.

Interesting that an oil specifically designed to mix with gasoline at 40:1 didn't at 640:1.

Even if you had dumped your total amount of oil used (84oz) into a full tank you still would have been at a ~30:1 mix rate. Which is what I run my chainsaw at.

If these engines benefited so much from such an inexpensive product the major gas companies would add it to their gasoline and maybe they do. Just buy top tier fuel and don't add anything. If anything throw in a can of Chevron Techron fuel additive.
I use either Techron or Gumout at every oil change.

LiquiMoly Pro-Line Fuel System Cleaner and RedLine SI-1 will clean your fuel system, and you only have to run them once in a while - either one of these, not both. Gasoline already has detergents, and it's a solvent to some degree. No need to waste money on fancy additives :)

I agree with Top Tier gas it's not needed, certainly not in every tank. But I do use it in a used car after using B12 or Techron to complete any cleaning. It's not the most effective but it is cheaper in many respects than other additives, and it is an effective mild FI cleaner. It also is very useful in power equipment where the pricey cleaners you mentioned are overkill......

Been driving for 50 years . Never used MMO or any of the fuel treatments . Hell , I don't even use " Top tier " gas . Somehow we have survived .

Whoa. This is almost exactly 2k miles of Pennzoil Marine Premium Plus at 640:1 in a EJ255:
