The rear diff, did you slide underneath or jack it up?I couldn't find a thread like this, so if there is already a thread please delete or merge.
Today I changed the rear differential fluid for the first time and changed the engine oil and filter for the second time. Current mileage is 13,028 and the vehicle has been great. Both jobs were pretty easy, though I am not a fan of the oil filter location. I used a little over 2 quarts of Honda Dual Pump II for the diff and 5 quarts of Castrol Magnatec with .7 quarts of Valvoline FS that I had left over from my CRV oil change (both 0W20) with a Fram TG7317 filter.
I need to do mine this week.
