Can't find my preferred Pentosin MTF-2 (GL-4), there is supposedly a recommended replacement Pentosin FFL-4 (GL-5) but I found a deal on FFL-2 which is TL 52182 rather than a more familiar GL-4 spec. The Dynamic Viscosity at -40C is strange at 12100 compared to other oils I've been looking at, will FFL-2 work? There is a problem sourcing exotic oils in Canada, I have gone through GM syncromesh unsuccessfully after a second change out with Honda oil. MTF-2 just plain worked for cold climate. 2015 Accord 4cyl MT6.
