yeah absolutely mate do what you reckon works for you! can't argue with that! Exactly reason I flushed mine despite my mech saying repeatedly "mate the oil in there is crystal clear, but do you still want to do it?" ... he agreed with the sentiments we both shared that it can't be possible to go hundreds of thousands of km's and not change oil. His foreman friend at Toyota, and indeed other toyota service departments have said to him / me , "it's good for hundreds of thousands of kilmeters, unless you do some exceptional amount of towing" ... and went on to say to my mechanic (a local guy, owner, trusted) are you really sure you really need to do it? "we simply never do them"... and added further "mate the WS oil really is magical stuff".
Either way... i agree, i dont think an oil can be that good, and hence I persisted with getting mine changed. herein, I will just keep an eye on it I think, if it starts to dirty... ill change it again. The oil that came out of the tranny was as clean as the oil going in
As to Kendall VersaTrans vs toyota WS ... I've no idea, can't find any info on kendal versatrans as to what exactly it is, or what it's "factory equivelant" is? ... only reason i went for factory toyota WS oil only was because I had COvs, Fuchs, and then one other vendor tell me that they recommend "type IV ATF oil" which is deadset wrong ... which made me basically distrust ANYTHING other than the factory-spec WS oil from toyota themselves. IN short, i feared that i'd get sold the wrong oil (and indeed was sold the wrong oil by covs / fuchs and got my money back...) and didnt want to risk it with the tranny ... especially because transmissions tend to be sensitive fickle beasts if you give them the wrong meal.
I'd be happy with non toyota oil normally (and i dont usually use toyota oils for normal servicing) but beacuse of the confusion i went with toyota WS only...
That said, the fact it was crystal clean after 120k has myself (and my mech) a bit stumped... my lux must had very light duties before i bought her that's for sure!! SHe gets a belting from me , and very, very hot and heavy work, but still its never skipped a beat, weird!
As to not totally agreeing .. which bit of my post did you mean?
