I do a lot of short trips, which isn’t ideal for my TDI engine. As a result, I end up with diesel diluting the engine oil, so I have to change it fairly frequently to avoid potential turbo bearing damage from fuel-contaminated oil. I’ve never used any additives before, but someone recently recommended Liqui Moly Ceratec. It’s a suspension of ceramic nanoparticles that bind to metal surfaces and supposedly provide an extra layer of protection against friction. I figured I’d ask here for opinions before trying it out at my next oil change.
Ceratec is good, its some type of boron based AW additive. It won't help your fuel dilution and itll be a waste when you short change your intervals
>>28925494they are bullshit. most tdi do short trips, i had several of them. they are made to do it stop making up problems.
>>28925494If the additives did anything, those very same chemicals would already be in higher end oils
>>28925561Boron is a common AW additive
>>28925494i havnt watched this one yethttps://youtu.be/IsjKLqUnwyU?si=eQEI3Th-pwr7jvaB
>>28925577Yes, it's already in higher end oils such as Amsoil, Mobil1 and Royal Purple. If it needed more, don't you think the oil engineers would have added a higher concentration of it? All the world's oil engineers didn't just all happen to magically forget to try anything that's in the snake oil additive bottles at autozone. It's a waste of money and unless you have an oil testing laboratory like they and Blackstone Labs do, you can't prove it did anything beyond anecdotal evidence either which is why they persist. https://blog.amsoil.com/do-motor-oil-additives-work/>Over time, wear protection will suffer if you use these additives, and so will your engine.
>>28925545+1 for ceratec, good shit right there.
>>28925494these oil and fuel additives usually consist of either a strong alcohol, diesel or a thick oil. if you want to clean up your fuel system, run through a tank of e85. if you want to clean up your engine, drain the oil and let it idle for 10-20 min on nothing but diesel as lubricant. it can take it just dont ever rev it. if your rear end grinds and you want to sell your car, stuff a banana into it. im not joking, it will silence a rear end long enough that all waranty is void.
>>28925494Oil engineers will tell you that additives actually hurt engines.The aftermarket additives tend to fight the oil additives.There's a lot of write ups from tripologists.Just change your oil more often.Or at least get the oil up to temp.
>>28925554>they are made to do it stop making up problems they are made to do it stop making up problemsI am just monitoring the oil level using the dipstick. It was exactly at the 50% mark when I changed it last year and now its 75% and climbing. I can't see how thats not a problem.>>28925545>It won't help your fuel dilutionThis I understand, if I understand correctly the idea of these boron nitride particles is that they coat the metal on metal contacts and provide an extra buffer against friction wear.>>28925545>and itll be a waste when you short change your intervalsThe label says to add it every 50,000 km so I assume that the fraction of surface-adsorbed nanoparticles persists across several oil changes.>>28925676>drain the oil and let it idle for 10-20 min on nothing but diesel as lubricantI am no mechanic but that can't be good for the engine. However, I'd make a wild guess and assume there are other additives that you dump into the oil right before change, let it run for some time and then do the change (the additive would've dissolved whatever insoluble deposits were hanging around the engine).>>28925698>Just change your oil more often.>Or at least get the oil up to temp.I change it depending on how much the oil level rises since the last change. Other than that I go for a highway drive once a week to do a DPF regen cycle (oil gets to about 95-103°C during the run).
>>28925545>>28925494I used it on my giulia (car was shaking at idle, sounded rough). Smoothed it right up.
>>28925600>>28925607>>28925676>>28925698>”trust the experts, it’s 100% safe & effective!Trusting authority is a sign of low IQ.Oil engineers are probably all retarded jeets at this point, and if not they usually just don’t want to waste time explaining the complexities of something to people whom they think are too stupid to understand. If 9/10 oil additives are garbage and 1/10 work in specific circumstances, instead of saying: “if your engine meets x,y,z criteria use Oil Additive #10” they’ll just take the lazy / safe route and say “don’t use any of them, ever.” But go ahead, put a modern 0w5 synthetic into your 1960s v8. The oil engineers know best and would never give you lazy advice.
>>28925792Using oil additives is a sign of low IQ. Additives increase engine wear.
>>28925792No car manufacturer is recommending you run a different weight of oil than what is called for in the manual.
>>28925792Ah yes, trusting some retard on 4chan instead, much better. >0w5 synthetic into your 1960s V8That would be on you for using the wrong viscosity of oil. You know modern oils in the correct thicker viscosities for those engines exist, right?
>>28925806>>28925809>>28925812>”you have to listen to me! I have a bachelor’s in engineering! that means I (maybe) know some basic theory and have zero experiential learning! you can’t just do your own experiments and share your findings, that isn’t scientific!!”meanwhile, in reality:> Ceramic oil additives like Cera Tec are built on sound tribology principles, and lab evidence supports their ability to reduce friction and wear under certain conditions.> Based on the physics and available testing, it is fair to say that:>The idea of nano or micro solid lubricants in oil is scientifically valid.>Properly dispersed ceramic particles can reduce friction and wear in certain contact conditions.>At reasonable treat rates, products like Cera Tec are designed to be filter compatible and safe in typical engines.These points support the general concept of ceramic additives as a legitimate approach to lubrication enhancement, rather than a purely cosmetic or marketing idea.
>>28925829Who are you quoting?
>>28925829Your bait is absolutely shit anon.I'm disappointed in you
>>28925494It’s really simple:>oil additivesBad>fuel additivesGoodTechron is probably the only additive you need since it has PEA (Polyetheramine) and the highest amount of it in any product, and will clean your fuel system.
>>28925809How are those bearing recalls going? Didn't GM get snookered into calling for 0W40 on their 6.2? CAFE , look it up
>>28925494Picking some time in your week to spend 30-40 minutes letting it get up to temp and then driving it at full temp would end up being cheaper than additives and cut the fuel dilution down.You could try blocking some of the radiator with cardboard. That's a common thing for winter in the US mid-north states. You'll need to cover more than you think
