Cat C7 engine capacity listed at 19 qts ,if I put 2 qts (prefill oil filter) can I then put 19 qts in the crankcase I instead of the 17 that I've been doing ?
Yes if you want to oil the car you tow. Two different oil pans for a 3126. The dipstick was added by the coach builder and have been know to be inaccurate. Maybe Brett... Wolfe 10 can help with how to identify which oil pan you have. 17 is the total amount of oil.
