I'm changing my front and rear diff oil in one of my machines. The last time I did the diffs on my cforce I used Lucas 80w90 gear oil and have no problems with it. I really was interested to see how I liked using the Maxima 80w90 because I'm a fan of their engine oil. The cheapest I could find it was on amazon for 18.99 a liter. I can get Lucas 80w90 local for $12 or Valvoline 80w90 for $10.99. My question is do you think it's worth it to get the Maxima oil for my machines? I change gear oil at least once a year front and rear in three machines if that matters.
Thanks
