Hello there,
I have a 2017 Suzuki Baleno, 4 speed automatic with 22,000 miles on it. The transmission fluid is looking slighty brownish with a trace of pink. It uses synthetic AW1 fluid however I'm unable to get it at any auto parts store. I googled for an alternative and found Mobil 3309. Is this a safe alternative since its an older fluid and is not synthetic? Also the properties of both fluids are very close.
Thanks!
If you can not find the exact one, one with closest specs should be fine.
Here are the specs:
AISIN Premium ATF 6:
Brookfield Viscosity @ -40 C, mPa.s, ASTM D2983 = 7450
Density @ 15 C, g/cm3, ASTM D4052 = 0.855
Flash Point, Cleveland Open Cup, °C, ASTM D92 = 200
Kinematic Viscosity @ 100 C, mm2/s, ASTM D445 = 7.10
Kinematic Viscosity @ 40 C, mm2/s, ASTM D445 = 33.10
Viscosity Index, ASTM D2270 = 185
Mobil ATF 3309:
Brookfield Viscosity @ -40 C, mPa.s, ASTM D2983 = 13000
Density @ 15 C, g/cm3, ASTM D4052 = 0.852
Flash Point, Cleveland Open Cup, °C, ASTM D92 = 198
Kinematic Viscosity @ 100 C, mm2/s, ASTM D445 = 7.1
Kinematic Viscosity @ 40 C, mm2/s, ASTM D445 = 33
Viscosity Index, ASTM D2270 = 181 (After running these numbers through a Viscosity Index calculator, the result is 185.92)
Do you think it would be safe? (I live in the Caribbean, no below zero temperatures)
Since you won't experience below zero degree, in my opinion, it is totally safe to use the Mobil ATF 3309.
