Why was it at the lower end? Dealers seem to have a hard time getting the oil level right.Well after my fix and totally cold weather I can not subscribe to the theory. My oil was actually on the lower end of full after the "Fix". The CRV is still cold and has the same cold engine as before.
I like the thought tho.
The upper dot...aka full mark.May I ask what the “expected” level would be?
Interesting Theory. The big question is just how hot is the Engine Oil getting? Is it above 212? Have people actually been measuring this?Theory:
The lower the oil level in your engine, the quicker the warm up and, by extension, less gas in your oil. The reverse can be true for heat though — the quicker the cool down when stopped, coasting.
Does anyone keep their oil level lower than the max? Have you realized any benefits?
And is there a significant difference in how quickly the engine heats up oil when there's one less quart of oil?Interesting Theory. The big question is just how hot is the Engine Oil getting? Is it above 212? Have people actually been measuring this?

I was expecting the oil to be in middle of the orange thing. Maybe the top dot on the dip stick.May I ask what the “expected” level would be?
Anything above the upper mark means the oil level is too high, which could indicate an oil dilution problem if you have a 2015 or newer CR-V.So......if the oil level is below the upper dot, the oil level is less than it should be?:confused2:
I was unclear as to what "oil was lower than expected" meant.

Not really. You’re omitting the fact that less oil creates less relaxation time and Increased cycle passes of the oil. This creates a non linear situation as far as evaporation of light volitiles in the oil. The easiest to understand is that with less oil, the oil will have a faster temperature rise, which will aid in timely evaporation of liquids such as unwanted gasoline. It’s not linear and simple as saying double the oil capacity would halve the gasoline dissolved.Less oil means higher dilution percentage - temperature is not a major concern as the heated fuel leaking around the piston rings is pretty warm to begin with after about 10 seconds. Just feel the exhaust - it is not cold.
The cure is a 6 quart oil pan instead of a 3 quart that the factory puts on. 6% dilution in 3 quarts is 3% in 6 quarts. Well below the 5% damage threshold. 1/2 quart is in the oil filter. To save $15 in oil and 3 lbs in weight we have a problem with oil dilution.
My 2 cents.
That is what the makers of GDI systems recommended to do when you converted from TBI to GDI. If you look at the larger engines like the Honda 3.5L they went to a 7.0 quart oil pan for Earth Dreams GDI engines from the 4.0 quart oil pan on non-earth dreams engine to lower the percentage of fuel dilution. Why Honda failed to do that for the 1.5L Turbo makes no sense. Honda's new cure it to make the MM go to 5% quicker so they won't have to repair lots of engines under warranty. With my 2 previous Honda 3.5L engines I almost always made 9000 miles to get to 15% on the MM. I wonder if the extra 1.5 MPG are worth the GDI shorter oil life and engine life if fuel dilutions is constantly over 5%. Maybe Honda is hoping the the faster erosion of the piston rings due to fuel dilution will cause oil to be burned faster causing the owner to add a quart of oil every 800 miles ending the overfilled oil on the dipstick.Not really.
