I would recommend you skip the amsoil and go with the valvoline maxlife synthetic blend from walmart for $11.97/5qt jug.
Oil Overfilled!

My manual says it takes 3.7 qts w/ filter at oil change. I add 3.5 each time and it hits the right level without worry. It varies by vehicle, so best to add a little low then add more if needed IMO.

There was a post from someone on this site about one of his relations who used to fill the crankcase with oil until it was up to the top of the fill hole in the valve cover. The gentleman got the car to around 200k that way before he sold it....
Incredible. A terrible idea and I can't see how that could work. Think of the extra oil weight and resistance against the bottoms of all the pistons. That must have created tremendous drag and internal pressures.
There must have been room and air pockets which absorbed expansion. Are you sure this really happened?
Hey Gang.
The oil dipstick is not a magic measuring device.
From the factory, my 98 f150 reads 1/2 quart low when its filled with 6 quarts and a new factory filter.
Its fine.

Unless you see foam on the dipstick, I would not worry. Foaming is the main concern with overfilling with gas engines.
Yeah, foaming is the symptom to worry about, I just bought another older Nissan, changed oil today according to manual, little overfill, took er for a good run, immediately checked for foaming while it idled, no foaming, perfectly clear, no problem, left it alone.
Overfill can pit crank, blow oil into filter housing, pressure up. every vehicle different. I agree with O1 ranger, if oil is not foaming, your okay. Next time I will put in a couple hundred mil less oil, then check oil level and carefully add to get the right level if needed.

I honestly think it's pretty rare to find an engine which can't handle a little bit of overfilling. Do you really think the car makers are going to tell you the absolute most oil you can put in the vehicle? They know they need to have some leeway there. So if the manual says 4.5 quarts for instance, you're not going to get foaming at 4.6 quarts! I would be willing to bet that you could run an extra half quart of oil in 95% of the engines built today. And I'm betting with my own vehicles in fact, I run a half quart extra in my wife's 2000 Civic and a full quart extra in my 98 Corvette.
The only problem I have had are the newer Nissan QR25DE 4 bangers, mostly because the oil check on these engines have to be done finatically at consistant spot, temp and drain time, oil dipstick reading very difficult and if not carefull one can top up excessively. It happened to me until I learned this engine, I had foaming, oil in filter housing, air in oil is not lubricating.
My older 70-80 Nissans were never a problem getting proper oil levels and little overfill on reading never effected them or foaming, the newer Nissans I just learn if they show reasonable reading on dipstick leave that sleeping dog lie or do damage. Been a lot of threads in here on oil level readings on newer Nissans, gotta be careful with them.
I bought one of first Nissan X-trails in 05, I brought it home right from dealership, checked oil, it was 1/2" above full line all the way up past the U on dipstick, it was a QR25DE, my 03 Altima had same engine and the dipstick full mark on it was true, I freaked even though there was no foaming. When I told dealership they freaked too, they checked every X-Trail on lot, all overfilled, they called techs, techs confirmed overfill on dipstick is correct as long as there is 4.1 litres oil in crank. Dipsticks thus probobly dont mean much on readings as said in here, foaming is a good indicator that something is wrong.
My sons current 3.1 chev, other sons 1.9 ford, my 87 Nissan,my 80 Datsun all take an overfill and dipstick reading easy and consistant, certain manufacturers, models can throw nasty curve balls, every engine tells a story and one has to learn what he can get away with or not with experience I guess.
