Oil Additives.

[jiujitsuheroS4]

What's up Audizine? (Besides your ceilings, the sun or the moon) I'm a new owner to a used Audi S4. I was wondering if these liqui moly or lubri moly additives are good for my engine. And do theybdo what they say they are mean to?

Thanks in advance..

BG MOA is the only good oil additive that I have found.

BG 44k is great to add to the fuel system on a full tank right before an oil change too. Really helps clean out the injectors and fuel system but it is expensive at $25 per can.

I have used couple of liqui moly additives such as mos2, ceratec, oil saver, injector cleaner, motor flush and valve cleaner. I spend a lot of money on additives but if I were to reuse that money, I would just get the ceratec instead of mos2 since it last longer. Oil saver didnt really do much for me if your car burns oil. Dont use valve cleaner since it doesnt work in our car. Motor flush didnt really do much to my car. Im guessing its clean already. Dont use seafoam on engine oil. It actually made my start up rattles even worst.. Injector cleaner works great but use it when youre close to your oil change. How many miles do you have in your car?

X2 BG109 to clean the motor WORKS because I did it and saw the crap that poured out (and yes its properly maintained)
The BG44 makes the engine run smooth as silk...only con is it's so damn expensive...

I wouldnt mess with the stuff. Just search for MOS2, ceratec, BG109 on bob is the oil guy and theres a lot of good info.....a lot of super heated debates over their merits as well.

I think the only logical way to tell if it does anything is to have a virgin oil analysis done of the additive itself, then of your oil, then a used oil analysis of just your oil after a given interval, and of your oil plus additive of that same interval. Then you would compare/contrast. Other than that, Im not sure how youd determine they did anything good other than looking at what came out of the drain (additives change oils appearance anyways) and by butt dyno.

Not to knock BG though, I use a fuel system cleaner ever 10k or so

Here is a good thread on this subject. As with anything having to do with oil..... see dparms posts.

I've tried fuel system cleaner at times in the past. I used it once previously in the S4 and was thinking of using it regularly. Techron, Regain and Redline being the best according to the experts on BITOG and dparm here. When I had my IM out I saw that my valves couldn't really have been cleaner. They had absolutely 0 carbon build up on them. If I do use it again it would only be once every 20k miles or so and not to clean the valves as there is nothing to clean.

As for oil...... instead of spending the money on additives and guessing if it's working, just send your oil to Blackstone for a UOA just before an oil change. I've done it a few times and after seeing the results see absolutely no reason to use additive in a good VAG approved synthetic. My oil after 5k miles was still good enough to go 7,500 miles per Blackstone. I did end up doing the next oil change at 7,500 miles, mostly because of lack of time to do the change, but also out of curiosity. I then had it analyzed and results were that it was still in great shape and I could go to 9k if I wanted (I won't stretch it that far though).

As I've always said, what is it about your current oil and state of your engine that leads you to believe you need to use an additive?

And if these additives are so great, why aren't they in every off-the-shelf oil? How do you know they aren't already?
