I'm 70 years old and i find it hilarious that when i was young people were discussing and even arguing about engine oils and change intervals.I see that nothing has changed. I change my oil twice a year regardless of mileage with synthetic. Last time i changed it had only 3500Klm on it. With the pandemic i didn't drive much. I just made sure i had enough toilet paper to last until i'm 89.

My old Ford Tempo is self changing. I just add a Litre once a month all is good. 😂🤣

[rickybroussard]

Being an Oilfield Mechanic for decades and working with both types of oil I personally found that synthetic oil is best in all applications

[Corb.ontheCob]

Tl;dr: the guy is saying that people who use synthetics go way too long between oil changes.
Saved you a half hour.

[bigmrfnB]

Project Farm has a great series where he tested a ton of a different types of synthetic oil.

[zachr]

A big thing with synthetic oil that people miss is that if they want more miles with the oil they need an oil filter that's up to that task, I've literally seen people go 10k with synthetic but they still had a filter rated to 5

[danwerkman]

Nothing like the internet to pick apart every word of someone that is talking openly. We must always remember editing and context. Makes people reluctant to talk on camera. This guy has loads of hands on knowlage....Thanks for the great videos

[Typersx]

I thought everyone in the north used maple syrup. 🧐

[jameskeyes]

I'd let that guy rebuild my engines any time. Honest, knowledgeable and experienced. The real answer for all this oil crap is the same as it's always been - preventative maintenance works. I change my oil and filter every 4000 miles in my car and 3000 in my bike and have never had a problem. No fancy oil, just regular Valvoline 10W-40 and name brand filters.

I change my oil once a year on my 05 Silverado. It gets 99% highway miles and only 6000 miles a year. It looks superb under the valve covers after 15 years of ownership. Running Mobil 1

[DFXKX]

A big takeaway I get from this is: Short drives ruin cars, as does going over your oil changes, especially in combination.

[Mikey-ljch]

8 min. In and had to say that this man knows his stuff. Ive worked in an automotive/diesel machine shop for years. What hes saying is the truth. Spoken from experience. Anyways love your content guys

[GreyBeardz]

Bottom line previous owner abused that engine. Oil type use is insignificant.

[MrJeffcoley]

The main “problem” with synthetic oil is all the people who believe it’s magic and never change it

[RedEarthAA]

I used to work for an oil importer. We had one of the engineers explain the difference between synthetic and mineral. It comes down to film thickness and film strength. Mineral oil has a high film thickness and lower film strength and better for larger clearance engines specifically cast iron bore. Synthetic oils have lower film thickness and high film strength and better for tighter clearanced engines specifically more modern engines or chrome plated, electro plated bores like in off road motorcycles. In my old Toyota diesel I use mineral and change every 5000km.

Give me a thumbs up if you spent 20 minutes rummaging through comments.

[markmiller]

Rich this was perfect, absolutely love the discussion and the back and forth. I could listen this type of content all day keep it up.

[bryoncovell]

As a shadetree mechanic, this video was very helpful. I never let my oil changes go that long, and always wondered why the manufacturer would claim such a long interval between simple maintenance. Just getting me to go from 3k miles to 5k miles was like pulling my own tooth.

[Taras-Nabad]

Although I agree about the short drives, you need to use your car when you need to use your car. The maintenance should match the driving habits. If you do frequent short trips, then the solution might just be to change the oil twice as often.

[akrocuba]

All my cars are newer and require synthetic. I change the oil and rotate tires, every 5k.
Oil is cheaper that an new engine
