Flush them out guys trust me they are hurting more than helping your engine. Just run a good quality oil with nothing added to it.

This is a good post to add to my oil thread. If you don’t mind, I am going to add it to my thread.

Go for it

Oh...... the motor oil Geek says oil additives are bad. I have to stop using them right away.

He uses a frother to mix it up and comments how much it foams up. Last time I checked a frother is made to introduce air into a fluid. WTF

skratch77

That guy is actually an oil engineer and makes oils for racing companies lol

sventastic82

lol

I suspect your crankshaft whipping the oil at 7000 RPM is probably having a similar effect to some extent…

sventastic82

That’s right, my bad. I didn’t know that the crankshaft is suppose to be submitted in oil.

skratch77

I wouldn't worry about that as much as the additive causing the oil to become acidic and lose viscosity

sventastic82

so you are saying having too much oil in it isn’t as bad as using additives?

skratch77

No but we all try to keep our top end from healthy and all this time we could of been causing the cams and valve buckets to wear out with adding additives.

Makes you wonder how some m156s with 90k miles have cams that look brand new and cars with 40k miles that need a whole top end done.

sventastic82

Good point.
My experience is different My first C63 had 150k miles and I used ceratec. The lobes and buckets looked perfect. It's the same with my second C63 with 60k miles. Both driven daily or at least every other day.
I think it comes down to how long the car sits in-between drives. It's usually the intake cam lobes and buckets which start to go first. That makes me believe the oil film isn't solid enough when started.

I have used ceratec or some other moly additive in all my engines since 2000 and never had an issue.
Makes it hard for me to believe that the oil geek really has enough data or examples to sate that all oil additives are bad.

There are plenty of other "experts" out there who would promote additives.

Unbelievers! This guy confirmed using his butt dyno that Lucas does indeed make your spark plugs bleed more horsepower:

Bingo. When the car sits, all of the oil drains back to the sump and there is no oil film between the cam lobes and buckets when you start it up.

eightysixtuned

he actually, didn't say anything negative against LiquiMoly MoS2 or LiquiMoly Ceratec other than the generic statements of, additives can dilute your oils additive package. also, that he designed a well designed premium oil that has all the right additives. and...buy an oil with all the right additives.

I think it’s important to keep in mind that Lake Speed Jr has a relationship with Joe Gibbs Racing/Driven Oils. Some of the additives that he alludes to are already baked into Driven Oils.

If what one has been doing successfully to prolong these engines especially with regard to cylinder bore wear on the m157 and the earlier M278, I’d keep doing what you’re doing.

Joshinator99

Not a Mercedes, but FWIW I run Driven Racing Oil in my 1059 WHP Camaro SS. Stack of time slips with mid 9 second passes at 150+ MPH. Tough to complain, oil seems to be doing its job. Stock crank, no less.

Diabolis

When the people that really know what they are doing - namely the triboloigists that work for reputable companies and design an oil to meet specific standards and specifications - properly blend a quantity of something in the oil during the manufacturing itself, it usually works. When a "Google certified" enthusiast / mechanic starts adding things to the recipe to "improve" it, it always ends up being worse than the oil by itself, and often very detrimental or sometimes even disastrous.

MB2timer

Done, and thanks.

sventastic82

Yes, he did. at 25:20 in the second video. Where Ceratec is combined with engine flush. Stating there is too much iron in it. which makes sense if an engine flush is used.

1Lop2K5C

That perplex me as to why he did a test of Ceratec + engine flush, who would run that combo in their engine? Would you just run engine flush 15-30mins on idle to flush before fresh oil change?

Lemons6245

He didn't say anything bad about Ceratec by itself. The actual data from his first initial test actually looks like it passed and he does not have anything negative to say about MOS2 or Ceratec . He then later points out a porsche i think that had Ceratec and engine flush which you can't necessary say that the Ceratec did anything wrong at all in that aspect. Without knowing for sure what exactly that person did it could be looked at as he added both and drove the vehicle around or they was still some of the engine flush in the system after they changed the oil, but to blame it directly on the Ceratec is misleading. I would say that he almost skips over the Liqui Moly additives for the most part and concentrates on others that have data to back it up. Notice how he never brings up any data at the end when he is talking about real world circumstance's of just oil and Ceratec, he only brings it up when it has engine flush.

Ultrakla$$ic

I noticed this same sentiment. He never shows data to confirm detrimental proof using Ceratec and MOS2, kinda glazes past it really. Oh well, if my engine blows, I'll junk the car and get another.

The main point was don’t use things that are incompatible. Some might be corrosive is used in too great a quantity or for too long, And don’t use too much of any additive as there are diminishing returns. All of my forced induction cars ate mobil one for breakfast, and adding mos2 and ceratec with motul has had those engines lasting a very long time with lots of miles between them using much less oil. Ceratec does settle and does get sludgy if you don’t drive a lot however..

A local shop had a sale on driven oils so I picked up a case for the next change in the m157. It just has strait motul right now. So will be a nice comparo.
