chefdave Posted November 11, 2013 Share Posted November 11, 2013 Dexron 6 does make a huge difference in my toy. still doing passive flush. now temperatures are now below freezing at night then add on wind chill factor auto box behaves faultlessly. hand brakes are left off as shoes freeze to drums. before the flush box was a little slow cold weather just made it worse due to oil thickening at dub zero temps. benefically side effect is an improvement in mpg and easier cruising. Think my oil was 24 years old so change is a good idea. Quote Link to comment Share on other sites More sharing options...
Derek up North Posted November 11, 2013 Share Posted November 11, 2013 Think my oil was 24 years old so change is a good idea. As a wise(?) man once said: "Clean is better than dirty." A flush with fresh Dexron II or III would probably have made a big difference too, but hard to prove now! Quote Link to comment Share on other sites More sharing options...
Vanman Posted November 28, 2013 Share Posted November 28, 2013 Was looking at the specs of various ATF's and the Castrol Transmax High Mileage has better numbers than anything, including their own synthetic. Anyone using this ? john. Quote Link to comment Share on other sites More sharing options...
Derek up North Posted November 28, 2013 Share Posted November 28, 2013 Which "better numbers" are you looking at? Quote Link to comment Share on other sites More sharing options...
Maineah Posted November 28, 2013 Share Posted November 28, 2013 Synthetic blend trans fluids do hold up to heat better, but I can't see one being any better than the other they are all basically 5W hydraulic oil. The new buzz word is "high millage" to me high millage starts some where around 250K. Extra coolers and regular trans flushes will give you the max life your going to get out of an over worked transmission it's pretty amazing that those little transmission last as long as they do they are pretty tough units.

Maineah Posted November 29, 2013 Share Posted November 29, 2013 The difference between d6 and d3is its a multi viscosity that is why is visibly thinner. I think what you mean is “multi vehicle low viscosity” ATF syn blend. has a low temp pour point in the - 50 numbers this is what makes it appear thinner and is more resistant to higher temps but the viscosity is of one weight. Dextron 6 can be used in Toyota's prior to 2004. Quote Link to comment Share on other sites More sharing options...

stamar Posted December 2, 2013 Share Posted December 2, 2013 im not sure where maineahs data comes from or what actually. but all toyota automatic vehicles produced in 2013 are recomended to use dexron 6 except for the lexus sports car it says to go back to use t iv for cvt vehicles like a prius. basically it is recomended for all toyota automatics except hybrids. My friends tacome it says dexron 6 on the tube. not toyota ws or anything iit says use dexron 6 Quote Link to comment Share on other sites More sharing options...

stamar Posted December 2, 2013 Share Posted December 2, 2013 nope im using dx 6, which is a multigrade atf. what about you/ have you ever changed transmission fluid on a vehicle youve owned? Do you have any pictures of this? Do you have any pictures of your toyhome? Do you have pictures of the tools you use to change the fluids on your toyhome? Im just curious. When was the last time you did any maintenance on your toyhome? Do you remember the year? i have owned 5 toyota automatic trucks in the last years. I have changed the tranmsission fluid Im going to say 10 times. What sort of experience do you have? Do you have any sort of reason at all why you think your opinion should be noted on this subject?

Derek up North Posted December 2, 2013 Share Posted December 2, 2013 all multi viscosity oil thickens with heat. You might want to read this. Perhaps 3 times. http://www.kewengineering.co.uk/Auto_oils/oil_viscosity_explained.htm Like most oils, the one you referenced (DX6) is thinner at 100C (5.98cSt) than at 40C (30.3 cSt). Quote Link to comment Share on other sites More sharing options...
stamar Posted December 2, 2013 Share Posted December 2, 2013 ok the first number is the pour number the 2nd number is the at heat number. what do you use to change your transmission fluid? what are the tools you use? quick grab them and take a picture for us. compared to dx 3, it has a much lower pour number. and a higher at heat number. whatever its rating is, and it does has one its just not written on the bottle, its something like 0-20w whereas dx3 is something like 20w. not those numbers, they might be more like 0-5w. there could be something tothe 5 w because even dx3 is pretty thin. dx6 is much thinner it seems like water. and if you cant figure that out theres nothing for you its an iq problem.

Derek up North Posted December 2, 2013 Share Posted December 2, 2013 ok the first number is the pour number the 2nd number is the at heat number. Where do you get this stuff from?

stamar Posted December 2, 2013 Share Posted December 2, 2013 i dont care dude its not relevant. Im trying to get what the hell you are talking about and why. I honestly have no idea. have you ever changed the transmission fluid on a toyota truck? Do you own a toyota motorhome? When was the last time you changed your own transmission fluid/ Where do I go look this up? I dont give a flying oooo what you think the 10 30 means it doesnt matter moron. haha i dont know why i waste my time. where in google do you look up whether or not youve ever changed the transmission fluid on your own vehicle?

stamar Posted December 2, 2013 Share Posted December 2, 2013 if you need to discover what multi viscosity means, its in the wikipedia thing on motor oil. yes atf is oil and its rated the same way. my god why are you here in this thread?

I knew i had seen that. If anyone needed any more embarrassing data that derek of the north knows absolutely nothing about vehicles at all heres more. modern synthetic atf is multi viscosity. Some people are so totaly out of touch with today data it shows obviously. real funny I guess except of course, you have nothing to add stop posting thanks. your total knowledge base is what you can randomly read in google in two sentences or less. with some really terrible reading comprehension.

Maineah Posted December 2, 2013 Share Posted December 2, 2013 In reference to your oil co.’s posting zero weight oil cannot exist. The confusion arises with the “W” the W is not weight it is winter. Zero any type of oil cannot be measured by viscosity measuring devices because you can’t have flow through any size hole in the device in zero seconds the weight is the amount of time it takes the oil to flow through a given size hole. So what is 0 W oil? It is a modified pour point it has been reduced with the use of synthetics to pour at a lower temp. Pour point is 5* above the point at which chilled oil shows no movement at the surface for 5 seconds when inclined. Now if you expect to be running your transmission at -51F you may benefit from a 0 whatever oil due to its lower pour point but beyond that is has no practical use.

Maineah Posted December 2, 2013 Share Posted December 2, 2013 So the 0W-20 Castrol I have in my garage is a figment of my mind? Just the zero. there is no zero weight oil just a lower pour point. The lowest viscosity is 5 it is based on time to flow through a viscosity meter the lowest time being 5 seconds if it was zero it would take zero seconds to flow through the meter that of course is impossible. Will it lube faster yes but only because of the pour point, great for turbo engines but the bottom line there are a very few of us that would have any need of instant oil flow at -51F even with a turbo so a 5W-20 oil would be fine for some thing around - 45F. The synthetic oil blend people love numbers that sound good on paper. As far as an automatic transmission all most worthless by the time the engine is running the automatic is pumping plenty of oil.
