Engine Oil Additives

[svard75]

Hi Guys, I'm thinking of adding an oil additive such as the LucasOil Synthetic Oil stabilizer and/or upper cylinder lube and fuel injector cleaner. Has anyone used it before? I have more than 100K KMs on this engine and use synthetic oil (M1) I also change the oil religiously every 3 months or 5000KMS.

I've used the Lucas Transmission fix and really liked the results on another car but wouldn't use it on our transmission's.

What are your thoughts/experiences on these products?

I always put in lucas oil treatment when I do my oil changes.

When you first began doing this did you notice a difference in the engine noise and amount of vibration? I wonder if you had any CEL or codes thrown since adding it?

Thanks,M

Why not choose an oil you feel confident in and skip the additive? Oil, especially a high quality synthetic oil, is precisley blended with a variety of additives in precise amounts to arrive at the desired finished product- upsetting this balance by pouring in additives may do more harm than good? Kinda like taking a chefs awesome recipe and "adding" a few extra ingrediants on your own, it usually spoils the dish!!!

In 244,919 miles on my Q, I have never used oil additives, and the engine runs like new....of corse, I have used synthetic since day one {Redline}

Folks, Lucas oil additive is not something I would recommend ... see http://www.bobistheoilguy.com/...s.htm for why.

If you are using a good dino or synthetic engine oil, and are changing on a regular basis (like 3750 miles or less), then adding anything to the oil is simply not necessary.

I saw that demo years ago and never considered it again. I do wonder if Bob had heated the additive up to the operating temps of the equipment when he did it. I never saw mention of it at a certain temp.

Even at start up though, until it was warm, I'd not want that in my equipment....

I remember the Car Guys talking about this a while back and they discredited this test for numerous reasons...none of which I can remember so take this with a grain of salt.

I had decided to use this based on the recommendation of the local shop that does any after-market work that I do not do myself. They are also NICO members. They did real world tests between changes in and apparently the change with the lucas was cleaner, and had slightly higher gas mileage than without. They use amsoil for there changes as do I. This was also in their track car and not a daily driver.

There are so many variables that it would be a really in depth testing process to see any real results.

Personally, I have noticed no difference in any aspect that I can directly attribute to the additive, but what I have noticed is that it takes longer to get to operating temp and the oil color isn't as dark at changes since using lucas. These may be unrelated to the additive though.

Wow thanks for that link. I won't be adding it anytime soon. But seriously how fast do our gears spin relative to his demonstration? An electrical motor can spin upwards of 20,000RPMS with ease ours spin at most 6,700RPMS so do you think it would still froth like that? Just speculating. I mean why are they still in business if it's not good?

Well, larger electrical motors will not spin that fast - usually those are the tiny ones. Plus, motor may have been spinning fast, but those larger gears inside the boxes certainly were not at 20k rpm for sure! Probably way less than the speeds inside typical engines ...

No idea. But, my guesses: (a) very, very few people actually spend time looking inside their engines to see what effect any additive may be having on things, (b) plenty of folks just buy whatever is at the auto parts store and try it out - usually when things are wrong with their car in the hope that the products will help and (c) sufficient new car buyers entering the market and auto stores that sales do occur, albeit not brisk, I suspect.

My bottom line: get a good oil and change the oil and filter regularly. Use a good dino if you don't want to spring for synthetic. In my 38+ years of owning cars with engines of all sizes (4, 6 and 8 cylinders) and types (inline 4, v-6 and v-8, and rotary) and many, many miles of driving experience, I have never had an engine die on me with regular oil changes.
