I currently use Valvoline in all my transaxles. It is all I have ever used in the last 30 years.

I believe you, there are plenty of folks here stuck in the glory days of yesteryear. If you are still using Dino 80w90 the technology moved beyond you about 25 years ago. I got a rotary dial phone that still works too.  |

Valvoline make both dyno and synthetic. Just because a company is 150 years old does not mean they don't modernize their products.

Hello Glenn:
Then I can use on my MEX 2003 the Valvoline VV831 80W-90?
Soon I want to replace the tranny oil, the car has about 14,000 km.
Thanks |

Will add to list thanks.
How does the viscosity compare roughly? VS, say, syncromesh or 75-90? |

Talked with Vic Skirmants (356 transmission guru) yesterday about my 356 transmission that he is just finishing up. Should be shipped to me this week.
Asked what oil he recommends. He like Valvoline 80/90 standard gear lube or any other major or brand. As for synthetic, he say’s OK but might have leaks. |

If you have an engine that seeps with 40wt in it and then go to a 0w30 oil it may leak a bit worse but probably not by much. I strongly suspect that it is the same for transmissions.
i swapped all my old engines over the synthetic between 10 and 20 years ago and none leaked noticeable worse than they had been before. Most cars dripped a lot of oil before the advent of PCV ventilation systems in the mid sixties, so as synthetic oils became more popular it would have been easy to blame synthetics for making older rigs leak extra oil even if the leaks didn't actually get worse. When I was a kid all roads had a dark oily buildup down the center of each lane, which was caused by both draft tubes and the engines of the time constantly dripping, yet in this day and age where synthetics and 0w20 dino oils are common that slick it totally missing because today's engines almost don't leak whether dino or synthetic oils are used. |

bruce I know what you are thinking ,I called them on this and since the only machine made to test the gl-6 is no longer in this world and product exceeded all gl-5 tests that's where they came up with the gl-6 rating.
regardless gl-5 /gl-6 rating , high torque load and easy shifting the product works very well in transaxles regardless of application

They're using false logic and false advertising then. If it had been previously tested properly and met GL6 spec then they'd be right to claim it, but if it's only been tested for GL5, no matter if it just barely met the requirements or it completely blew them out of the water, it still only meets GL5 spec.

False acusations....!
Prove it doesn't meet the spec. 
The GL rating is fairly meaningless as far as determining if an oil is suitable for use in a syncronized manual transmission anyway. The 60 pages is proof of that.
On the other hand if it DOES say it works good, and it doesen't, then that's newsworthy. Closest thing I heard to that was maybe redline, maybe. |
