I don't know what is in Lucas. I do know that I used it once in my truck and it didn't run well at all. I had to run that tank of gas down in a hurry and refill to clear it out. I have read that Lucas is mostly just oil and has no real cleaning agents or abilities. I don't think Lucas does very much to couneteract the ethanol in fuel either.
MMO is hands-down the better of the two. MMO will lube and condition the fuel pump, fuel injectors and the entire fuel system, and it will help restore the lubricity that is lost in fuel due to ethanol. It will keep the spark plugs clean and help them to fire better and it will condition the cylinder walls and piston rings to increase power and compression. I think the improved performance from using MMO is also what contributes to the slight MPG increase I get from MMO in my fuel. MMO is a mild cleaner that will help keep the fuel injectors clean but you have to use it regularly in every tank. The best way to put it is to use a good total fuel system cleaner like Regane or Red line SL-1 first, run that tank down as far as you can and then start out using MMO in every subsequent tank. The idea is to get it clean with a fuel system cleaner first, then keep it clean with MMO. I still use Regane or Red Line every 6,000 miles, just before every other oil change. On those tanks I do not add MMO at all. I go back to my regular MMO dose on the next tank after using Regane or Red Line.
MMO is great but it is not a magic bullet. You have to use it consistently in every tank of fuel to get the full benefits from it. For me personally, when I started using MMO it took a couple of tanks of gas to begin to see the benefits. Some have used it and noticed improvements right away. I carry it with me in my truck at all times in an empty small diameter bottle from the new concentrated formula Regane. I save my empty Regane bottles just for this puropose. It's a lot easier to dose the MMO that way and I don't need to carry a funnel with me to add the MMO. That is the only bad thing about MMO for me, the MMO bottle itself does not pour easily into my tank. I just measured and made a mark on the Regane bottle at 6 ounces, which is the MMO dose I use. I fill up when my gas gauge gets to the 1/4 mark and it usually takes right about 15 gallons to fill my gas tank. 6 ounces of MMO to 15 gallons of gas is the right dose for my truck. I had to experiment some to find that out. You may need to do the same, but I would say start out at the recommended dose of 4 ounces to each 10 gallons of gas. On your first dose add the amount of MMO it takes to fill the entire tank. If you have a 20 gallon tank, add 8 ounces of MMO. On each subsequent tank, add only the amount of MMO that corresponds to only the total amount of gas you buy. It is also best to add the MMO to the tank at the pump and then fill up with gas. This is the best way to mix the gas and MMO.
My truck runs very well and I get a slight increase in MPG with MMO in the fuel. I track my gas purchases and MPG on
www.fuelly.com every time I fill up. I have added it to my oil a few times as a cleaning agent and some use it in their oil all the time. You can substitute MMO for up to 20% of your oil capacity. I started using Quaker State earlier this year and it is such a better oil than what I had been using before that I do not see a need for MMO in my oil now. MMO in the oil will quiet noisy lifters and help give a smooth even idle and in cold climates it can really help on cold starts.
This is probably more info than you asked for. But MMO is a great product and I always say my only regret is I wish I had started using it a lot sooner. I have done my own testing and experimenting with my truck and I can say without a doubt my truck runs much better, has better power and a smoother idle and throttle resopnse and it gets about 1 to 1.5 better MPG with MMO than it does without MMO. This is my experience with MMO. My truck does much better with MMO than it ever did without it.
