A good tip for oil that fills slow thru the top. Try pulling the dipstick out a little bit. The top of the engine may have small ports and the air that needs to be displaced has nowhere to go. Pulling the dipstick out a little will let the air come out thru the tube. I learned this years ago doing forklift maintenance. Some of the older Japanese engines like the Mazda M4, Nissan H20 and some others had very small pushrod passages under the valve cover and the oil would hardly flow unless you pulled the dipstick out a little. With today's overhead cam engines with high quantity of oil in upper part of engine while operating, most all have good drainage up top to get that oil back in the pan.

I look up engine code and specific tolerances and temperature. You'll find the manufacturer of the actual engine will have significantly different recommend oils. For example my 2019 accord takes 0w20 from the factory which is adequate for light duty in most of north America. When you look up the engine code you'll find very specific tolerances and recommend oils. I run 10w30 as recommended directly from Honda for my engine and 5w30 in the winter also recommended from Honda. My manual, or vehicle does not give any guidance at all. If I listened to the manual I'd have increased stress on my turbo and engine at high ambient temps

You should use a torque wrench to tighten the drain bolt. For a mechanic like Scotty who's done it million times, he may have a feel for all kinds of torque, but if you changing your oil for the first time, and don't use a torque wrench, you can either get it too tight and strip the threads in the oil pan -- HUGE HUGE PROBLEM as you won't be able to drive the car even to a garage -- or put it too loose and risk loosing the bolt on the road -- again a huge problem because if you lose oil on the road you will destroy the engine and will have to tow the car in any case.

I have a large estate car, (I think you call this design something else in N America ) underneath there is a huge plastic protective shield. The car is too long to get it up on ramps, high enough to get access to the plastic. Another car video suggested an oil pump, via the dipstick tube. I used this with the oil at max temperature, so the pump and container were red hot. Total clear out, I think.

Scotty Kilmer I disagree on the oil viscosity the manufactures say a specific weight w5-20 or w5-30 that contributes to gas mileage they rate on the sticker window. My Ford Ranger says 5-20. My engine has 75, 000 miles and has worn in so now I run W5-30. I will update you at 200, 000 miles and see if the engine has blown up by then.

I've been changing my own oil for the last 18 years and I've never changed the drain plug gasket. I don't even care to check if it had one or not and I've never had problems with leaks. Leave it to Scotty to make me worried about my oil changes from now on. Because of course I'm doing it wrong.

I always change the gasket on the drain plug, for no leaks. Guys at work always ask why do i always do that, itll be fine. Then, the guys that do an oil change, will have come backs and the customer saying they have an oil leak. And come to find out they didnt change the gasket. Lol

The torque on the drain plug on my car is under 20 foot pounds why would I need a breaker bar? That's not smart. If you need a breaker bar it's too tight. and oil filters should be hand tight there shouldn't be any need for any oil filter wrench. I thought you were old school Scotty?

For someone who is telling me I am changing my oil wrong, Scotty forgot to prime the new filter before putting it on. Scotty should know that the most amount of wear that occurs to your engine is during a cold start after changing your oil (if you don't prime the filter.
