i dint drag u in lah, i just said u did the changing atf and filter of the car.
maybe it does what u said to my uncle's car but they did claim lubegard will solve gear 'morning sickness' and they did that. hard to believe when my uncle's keep changing with good atf(not synthetic) every 20k and he already have this 'morning sickness' feeling since 2-3 years ago.
he poured in half bottle lubegard red and the next day no more 'morning sickness'.
i dont recommend it on new car, only car got similar problem with what i said.
Well, if your uncle has been using the correct oil and is always filling at optimum levels, then I'd be surprised. But if he was always overfilling or underfilling without realising it then he'd slowly kill the gearbox hence the problems now. Lubeguard *probably* changed the viscosity level (I use this assumption
very loosely) to cater for the higher wear and tear.
In my Myvi's case, I cooked the gearbox because I ran about 20km+ without any oil in it because the hose had cracked and leaked all my oil out. So I probably do have damage inside the gearbox hence my issues. Lubeguard may or may not fix my problem but I'm not willing to spend close to RM100 to find out. Good fully synthetic oil like those from Rockoil or Pennzoil seems to do the trick for me except the gear changes aren't as smooth as they used to be.

reason being coming from an engine oil point of view, base oil itself won't last as long as what reputable brand/expensive engine oil can. the additives is what prolong the oil's life, prevent it from degradation from carbon/other waste deposits from combustion, and of course enhances its functionality be it less friction, or even better and/or consistent oil viscosity etc
in contrast to ATF additives/oil in line to what i've said earlier, i am a believer of liqui moly and torco semi synthetic oils. the difference is just so huge compared to a "reputable brand" mineral oil (or even semi- synthetics)such as shell, hi-rev and so on.
You are right and wrong at the same time.
The additives determine the viscosity, the amount of detergents, anti-acidity additives, heat suppressors and a few other small little things yes.. preventing it from degradation no.
There are a few grades of base oil, most engine oil brands these days use group 3 base oil which is the lowest quality that can be used for engine oils. Grade 4 and 5 are ester based oils and they are way superior in lifespan and heat transfer etc. Expensive oils like Motul (the ester based range) and Ravenol (I don't know the makeup of Torco and Liquimoly) use group 4 or 5 base oils hence their price.
It's kinda like comparing a car tinted with cheap tinting. It'll protect your interior from the UV and some IR. But put it side by side with Vkool Elite and it's a completely different thing although they both do the same thing. In most cases too Vkool Elite will outlast the el-cheapo tint because of the quality materials it's made from.
So you're right about you get what you pay for.

not API certified. 'Exceeding API certifications' and compliance to the certification requirements is not the same thing.
I wouldn't use an oil that hasn't been tested and certified otherwise they can claim the whole sky and earth, and no one would be the wiser.
