    I love to run lucas oil stabilizer in with my mobil1 personally. Stuff is thick and helps the viscosity of my oil last longer.

    Re: anyone using oil additives?

    I use Lubegard engine oil treament (in the blue bottle) with my usual Amsoil 5-30W Full Synthetic. 183,000+ miles on my 2003 and doesn't use a drop of oil between 10k changes.

    Re: anyone using oil additives?

    To the best of my knowledge, all oil companies recommend against additives as they state the additives may work against the formulation of the oil. I know that AMSOIL recommends against it. My opinion is that they are not worth the money. Use a top synthetic, change the oil per the OLM and you'll be fine.

    Any good oil should not be tampered with. The oil engineers know what they are doing. Especially when you're talking about a healthy engine.

    Re: anyone using oil additives?

    In regards to adding Engine Oil Additives, my 06 Owners Manual has GM's position in the excerpt below.

    I don't add any oil additives for daily use. However, once year or so, I will add a 1/3 can of Sea Foam to the crankcase of a warm engine, drive 15-20 roundtrip miles returning home, then immediately change the oil/filter and only add Mobil 1 Sync 5W-30.

    Can you explain this please?


    I have never used any additives. I use royal purple oil, anti freeze mix, differential oil and transmission oil. If i were to use an additive, it would be zmax.

    Not taking a cheap shot or anything, but some say Carroll Shelby endorsed a "Snake Oil" product purely for the big bucks. Do know that I bit back in the 80's with "Slick 50" additive. Can't say I ever saw any real benefits, but at least it caused no harm.

    .......
    I do see more benefits using additives for cleaning fuel and intake systems.

    Re: anyone using oil additives?

    There is no reason to add anything else to your oil if you are running a top tier oil. I run Mobil 1 in my truck and wife's CTS. Run Royal Purple in my track car. Neither of these products needs additives to "help" them last longer or get thicker. In fact, you don't want them to get thicker. Stick with the factory weight the engine was built to use. Going from 5W-30 to say 15W-50 because it is summer time also is not required, yet many of us did it. I run the same weight oil year round. I don't bump the weight even in my track car.

    The Sea Foam idea is no different in the oil than it is in the gas. It's being used as a detergent to clean things up. In the gas it cleans tank, fuel lines, injectors, valves etc. In the oil, right before a change, it lightens the oil weighting significantly and its detergent properties help liquefy sludge and and other junk to get it to the bottom of the pan so it will drain out.

    Anyone who thinks these additives are required has been snowed by the BS of marketing.

    Here's the simple way to demystify the BS. Pick a mileage interval, say 5,000 miles. Just use your top tier oil with no additives and your favorite oil filter (use a good one). Drain oil and catch a sample and send of to Blackstone Labs or equivalent lab. Now change oil and filter using exact same brands. Add your favorite "snake oil" to the engine. Run for same mileage and repeat the sampling process. Compare lab reports after. At best you'll find a few chemicals that have more life left in them. However the original oil only sample will still have a sufficient amount left to meet the need. This has been proven over and over.

    Then again if you're really ballsy... go ahead and use that super additive that lets an engine run without oil. Put it in and pull the drain plug. Video tape and post for us, we could all use a good laugh.... ;-)

    I was thinking of using Lucas synthetic oil stabilizer just to keep everything lubed between starts

    No need. Synthetics get to the top of an engine about 6 times faster than petroleum. If you're changing your oil when you should and you're using quality products there is nothing more to be concerned about.

    SeaFoam is a brand name for a product similar to this offering from AMSOIL:
    AMSOIL Engine and Transmission Flush

    Really only needed for an engine you believe may have sludge buildup, particularly if you are changing from conventional oil to synthetic in this situation. In general, synthetics have more detergents, and/or they are more naturally detergent, so for an engine that may have lots of sludge buildup, using a product to get the sludge out is needed. Alternative is the oil cleans the sludge out in use, the sludge blocks some vital oil path during operation, and bad things happen to the engine. For engines that have been well maintained with oil changes as required, this is almost never needed.

    I am using SeaFoam in my oil for the next few oil changes because I had sludge build up in the engine. I was shocked how bad it was when I did the timing chain job.
