I was skeptical that it would make that much difference, but now I am a believer!
hmmm... time to return the 10w30 GTX i bought
0w40 synthetic you say
well i just switched to petro 5w40 full synthetic will see the difference when it gets cold again
Frisco auto parts in Mississauga carries Manhiem oils.They have a great full synthetic 0W40 and 5W40 which are extended drain (I go 10K),and really cheap.$24 for 5 litres.I have also used the Rotella 0W40,it works well too.
rotella 0W40 synthetic in winter, (canadian tire on sale) and 15W40 in summer.
Pentosynth or Castrol Syntec (not the one for gassers) 5W30 during the winter, Pentosynth 10W40 during the summer.
really, its personal preference. lol, i was running castrol enduron 15w40 semi syn all year, now i switched to syntec 5w40 for this winter, liking it very much for the starting, think i may run that all year, any 40 weight oil flows the same once its hot, so if u want to run 0w40 in the summer, its the same as 15w40 once its hot, its just flows better at lower temps.
