when did you get your 1st oil change (what mileage) for your 392?
I agree....... even If I was using Dino oil and was pouring 7 qts, I would still go 5K on a 8 cyl city driven motor.You guys change your oil too frequently.
1,000 was my first. Mobil one and Filter for me, I'm at 2900 now just checked it, and it's Super CLEAN on the stickMost vehicles I have owned, I have followed this procedure
At 1k change
At 3k change and every 3k after that.
I may stick with this routine with the 392 but if I do not, it will be changed at 500 miles then at 3k and every 3k after that.
