That’s the stuff my Toyota manuals are supposed to use, but I run Pennzoil Synchromesh in them, it’s a lot thinner in winter conditions. Around 0F regular 80W-90 gear oil is like stirring a bucket of jello with the shifter!It is rated GL4
A bit high in viscosity (17 cSt@100C) for a 90 grade transmission oil; most come in around 14 cSt.It is rated GL4
But would this Castrol product have friction modifiers ?
Is there another Castrol product that would be preferable ?
Thanks guys, the car is not mine, it belongs to a friend in Southern Europe, so temps get quite high. He favours Castrol products in his British car.
What would a recommendation be if an electriclly operated wet clutch Overdrive were coupled and shared lubricant with the transmission ?
