So How Much Oil Is Too Much? ⚠️- See Why It Really Matters!!

- Yes you can have too much oil and it can cause catastrophic engine damage, but how much oil is too much? At what point does the level of oil over the dipstick cause problems and issues?
After our previous video explaining the damage that happens from having too much oil, and the massive amount of feedback from people who have suffered from this we thought it prudent to help quantify how much oil is REALLY too much.
We've heard about garages overfilling the oil, owners forgetting to drain the oil and topping up or double fills that happen when you have multiple mechanics working on a car.
There is a big difference between one centimeter over the max level on the dipstick and a couple of inches (10cm) but as all engines are different and sump capacities and engine designs vary it would be handy to understand how the sump and oil pickup works and see inside an engine and witness for ourselves how the crank moves through the oil.
Many are paranoid about going over the dipstick max level, does it matter that much? How much of an overfill of oil can you get away with before damage happens.
We have to accept that all engines are unique, some are more tolerant than others, but looking inside the engine, at the dipstick and the sump we build up a picture of what is going on and where we are most likely to see a problem with too much oil in our engine.
If you have overfilled your oil AND ARE GETTING SYMPTOMS as discussed in this video then drain off the excess as soon as you can. See our video on the damage that happens where we go into more detail as to what is happening inside the engine and how engine damage occurs.
In some cases the wear and tear is accelerated so you might get away with too much engine oil for a while but after a while this will catch up with you. In other cases you'll get rough running, burning oil, oil leaks and vibrations from inside the engine.
Don't ignore any of these symptoms. We show a few engine internals in this video to show the differences in crank clearance and oil pan design, to help you build up a picture of how much oil is too much for your engine.

Over filling will not affect oil pressure. Oil pressure is controlled by oil temperature, viscosity, engine rpm, engine wear/ tolerance, pressure control valve in the pump and pump design in general. But if your engine normally hold X pressure at Y rpm. Adding a quart/Liter to the oil pan will not affect X if everything else is the same.
Oil with air incorporated will have the same viscosity ?
I love the american consideration of importance of feelings.. How much oil you feel is too much? Yeah, it's about the feelings from the bottom of my soul!
Thanks for the vid!
On my 14 mazda 6 it calls for 4.8 quarts/4.5L but putting in that exact amount puts it a little half on the dipstick. I run it like that any ways and have had no issues. Now i work as a oil lube tech and i do a lot of oil changes and have done many oil changes on many different 2.5 sky active Mazda 6's, Mazda 3's, ect. You can tell whether the car was built in japan or mexico by looking at the vin number and one thing I've noticed is the Japanese built ones like my mazda 6 the dipstick reads low with 4.8 put in. But on the Mexico factory-built ones the dipstick reads full with 4.8 put in. Ive noticed that the dipstick wont quite read full with a couple other cars to. My thought is that the dipsticks designed to read full after the oil is hot on some motors so when the oils cold it will read low but once you drive for awhile and get the oil temp up it will read on the full mark. Idk if thats true or not but its what ive experienced with my mazda anyways.
I have run all my engines a quart over full. Going to help with oling the pistons and timing chains and lifters. Why you think they have oil squitters shooting oil at the pistons and rings. They never oil squitters years ago. They over baffle engines today just for a little better gas millage at the expense of the engine which you pay for after the warranty is gone.
If you have a EA888 engine - if it’s at max on dipstick on level ground add exactly 200ml and that is where you want to run a EA888 engine (any and all years) no less and no more. When my dipstick hits max level then I know to fill with exactly 200ml to be spot on. Hope this helps anyone else with a EA888
Great video. Very informative.
On my 3rd Gen Prius, the PCV valve is horizontal on the block. Too much oil and the engine will be throating raw engine oil. Toyota says 4.4 quarts but I only fill to 4.1 quarts so as to minimize the oil that’ll pass into the PCV tube.
I don't overfill any of my engines, but I keep them at the max level. They build up oil pressure faster and a bit reserve if they should start leaking.
I do overfill my differentials by jacking the vehicle up. A differential will push any extra out of the breather. Not a lot of extra fluid, maybe an additional few percent (example my dodge truck 8 ounces higher with a standard capacity of 100 ounces).
I have a Polaris sportsman 570 that has a notorious front differential issue where the bushing for the pinion gear is notorious for wearing out anywhere from 700-2000 miles. I have 6000 miles and mine is nice and tight.
I do not overfill any automatic transmissions. I follow the manufacturer's instructions.
Just my $.02
Interesting, thanks for sharing my friend.
Really informative video.
Glad it was helpful! Thanks buddy.
Watching this after I overfilled my 1.8 TFSI. I checked the oil through the multimedia interface while driving the car and that gave me a wrong reading and I added a full 1L of oil after checking it like that (it was at min but no oil light on). Now I'm pissing my pants in fear that I permanently damaged the engine :(.
Oil started to appear on the head cover and I changed the timing cover and gasket thinking that was causing the oil leaks. Also oil started to appear around the head cover gasket.
I drove the car like this 350km. I will do an oil change tomorrow and check the damage (hopefully there will be none) with a mechanic.
How did it go my friend? Did you get away with it?
@@torquecars too much oil explained why oil appeared on the head cover, luckily it burned through it pretty quick (I drive it sporty) and didn’t do any damage (mechanic looked at it). Also i drove it like this more than 350 kms :))))
Walmart overfilled my 2.4 VTec by a small amount. Is that cause for concern? I've been freaking out about it. It's the first time in my life I've ever taken my car to have the oil changed
No don't worry, a little over seems fairly routine for garages and dealers, I guess they assume people wont top up or check.
