- is the lower bound value 9.8 cSt of the 75W-85 series a white paper value ?
- is the viscosity curve (temp - cSt) linear ?
- for cold weather replacement the value at 0°C would be much more interesting than at 100°C.
may be it is a good compromise to go away from multi-range oil and change the oil when tires are changed in spring and autumn like dailydriver is doing.
@MolaKule:

75W85 Series-Type; 9.8 to 11.5 cSt ( Redline's MTL, RP's Synchromax LT, Nissan's MTL, Honda MTL, Castrol Syntorq LT)
Castrol Syntrans V FE 75W-80 is round about 2 cSt away from the lower bound of this range.
Is 9.8 a white paper value ?
2 cSt...
@molakule:
yes, I'm experiencing cold weather shifting problems. The time span from starting the car til the oil is really warm.
The problem exists only when shifting from 1st to 2nd and back.
My concern is not wear or failure in the cold.
My sorrow is that a 8.0 cSt oil is much too thin in...
looking for a replacement fluid:
temps outside now are about 0°C and in the middle of winter they will go down to -15°C.
For my car MTF 75W-85 API Gl 4 is required according to the manual.
No specific fluid (brand) is required. So I dont know the 100°C viscosity of the original factory fluid...
Jeff_in_VABch: a lot of thanks for your very helpful and competent answer !
I think your diagnosis is very likely.
But what I observed is, after switching to Redline MT85 in the gearbox the whining was nearly gone. It was in early spring. Now in early summer the whining is back. Maybe the...
currently I'm using RL 80W-140 GL5;
Assuming that the slight noise could be quieted by lube, what brand, weight, type would be the best option ?
If Schaeffers is it, what # of the following would be the most reasonable ?

Manual transmission 5 speed
Hyundai Grand Starex / H1 / H300
2.5 Liter Turbocharged Diesel Van
mileage: 55.000 km
tried already different synthetic diff lubes with varying results
be aware of the speed range 80 - 100 kmph, typical for all causes ?
Hi guys,
- above 80 kmph at the point of loading (acceleration) and unloading (deceleration w/o using break) there is a slight singing / whining from the rear
- the same singing is present in idler neutral gear between 80 and 100 kmph (just as additional info)
I dont know if it comes from...
