dealers charge for 8, but don't use 8.

i wouldn't over fill. more oil + oil pressure can blow seals.

Rnl, are you saying there's no such thing as overfilling an engine with oil? Or that 8 qts in a 5.0 is not overfilling it?


I just use 7 and 3 quarters as a ballpark figure for getting the dipstick level dialed in, and then I pour more in until the level is close to the top of the hash zone. Idk if that comes out to exactly 8.0qts but it really doesnt matter.. Pay attention to the dipstick and this is a non issue that doesnt need a thread started over it.

You put in 8 qts with a new oil filter and by the time the oil pressure reads anything, the filter is filled with clean oil and the oil pan level normalizes--bingo, you're gold.

I have worked on lots of different engines, huge and small, diesel and gas. A little extra won't hurt.
You would really have to overfill it to do some damage, again, depending on the engine, size, ect.

Honestly, I used to be super particular on machinery I worked on. That was when I was a "noob" apprentice.

I was shown the way by veterans though.

That being said I used your method on past personal vehicles. I plan to with my current truck once I start changing it myself. I'm **** like that.

Unless you overfill to the point where the crank starts slapping the oil...you are ok. Can cause too much air (foam) in oil.


Some vehicles benefit from a "bit" extra oil...can lessen start up piston slap noise...SCCA Showroom Stock cars often add a bit extra for high g-forces.

Why not fill up to 7.5 quarts and save the other half quart for the next oil change?

gDMJoe

Because you would have under-filled the oil (according to the recommended spec').

I prime the oil filter with ~ ¼ quart of oil and then put 7.7 quarts of oil in the crank case. The dipstick always measures to the top of the max hash-marks (where it stays until the next oil change).

I'm saying there is no problem adding that little bit extra.

This exactly^


Many moons ago I had an oil change in my stall, was a Honda or some sort of import, don't remember what but I left for lunch prior to refilling the engine with oil, someone else in the shop came in and put the required 4 qts without telling anyone so I came back and commenced to put in the 4 qts as well, I thought something was odd when it started backing up in the valve cover but dismissed it to being an old engine that was probably just clogged up with crud from lack of oil changes.

Then I started it and James Bond would have been proud of the smoke screen that filled the shop and choked us all out to the street

While letting the smoke clear the answer was soon learned what had happened and the dumbass that had no business going into my stall was let go, wasn't his 1st screwup, just the proverbial straw breaking the camels back.

That was an overfill to remember.
