What is the average life of a stock 4.6?

I know it has to do with how previous owners take care of it but what is the most miles that the 99-04 4.6l can make it through?

Well, if you take care good care of it just like with any engine you make it well into the hundred thousands. But if you don't take care of it then it wont last long at all

I would say great condition with constant checkups and replacing Known worn parts... 300,000 or a bit more

My 96 gt had 400k on it when I sold it and it still ran like a top. Replaced the intake manifold once and that's it. I ran that car hard too. In 110 degree heat and -40 in the winter. Great car... miss her a lot. Guy I sold it to parked it in the back of a semi a month after he bought it...

Wow man. Thats a Lot of miles! Although thats def. possible! I would go in between that range.. It all just depends on how its drivin. If it was for a manual and the guy sucked at drivin stick, then not long but an auto, itll last quite a while

Yeah I had a manual. Shifted it hard but clean. I ran that car pretty hard but also took good care of it. Premium gas, high quality synthetic oil, premium filters and cleaned it weekly. It had the stock clutch replaced at 110k and the next one at 335k. When I sold it the car ran low high 13- high 14 depending on track conditions, 60-0 in 118 ft and 0.96skidpad. I ran 911s down on the road courses often but I would never say I'm as fast as a 911 but I was a better driver than every one I raced. Life of a car is directly related to how you treat it and how you use it. A driven hard car well maintained is better imo than a quicky lube maintained dd.

Re: What is the average life of a stock 4.6?

Police forces and cabbies have run some of these engines 300k or more. But you need to take care of them. Regular maintenance is the key.

I bought my Crown Vic with over 150,000 miles on it and at 177,000 miles, it still pulls hard. But regular maintenance is the key.

Once sold a Chevy Impala wagon with the smog 400 ci with over 225,000 miles, and it still ran the way it was bought new. The guy who bought it had a valve job done at 235,000 and they found little carbon buildup on the pistons. The engine finally died at about 300,000 miles.

But all my cars receive regular oil changes at 3000 to 3500 miles, lube jobs, monthly washes, all repairs done as soon as possible, regular cleaning.

Treat your ride like its still new daily and it will be at 200,000 miles.
