[QUOTE="Lazy-Farmer, post: 6648387, member: 143591"] I understand the difference between engine oils and hydraulic as their is a whole lot of other stuff going on when you add carbon from combustion etc. So we have one person saying never use 46 in a tractor transmission. One saying it’s a suitable substitute and another with some very good info. I’m still not clear. obviously saying 46 is a generalisation as you get dozens of different oils in every grade. Mainly 32, 46, 68 etc. But which of these is a UTTO. I am trying to work out what a UTTO actually is without having to get some sent to a lab for analysis. I realise I could just go get the manufacturers stuff but I’m a bit off a geek when it comes to this kind of thing and although I know a bit about oils I’m no expert but keen to know more and understand what makes them different and worth the price tags Realistically it’s only a few key things that change if they are rated to ISO standards. grade 10w - 32 15w/20w - 46 20w - 68 (It’s my understanding that Multi grade oils ie 10w-40 are 40 grade oils with a a low W number meaning it’s good for colder wether than a 20w-40 for example.) Additives - anti foam, anti wear, corrosion inhibitors, anti freeze agents for low temps etc Working Temp range Flash point vapour pressure I can’t seem to find the info for the super universal oils or the UTTO to explain what’s different about them from a good quality AW oil of the appropriate grade. Is this that manufactures don’t want to give full data sheets so you can’t properly compare them? [/QUOTE]
