bad about vehicle setting the oil additive molecules will eventually separate which usually takes years. Why the recommend don’t use oil (any OIL) over 5 years old.

Sure you can oil tested but eventually that defeats cost oil change.

You'll be able to pick up on contamination or impending bearing or ringland failure with a high presence of wear metals.

I generally use them a few times on each new vehicle to gauge health of the engine, how it likes the particular oil used, and if it need to be changed prior to mfg recommendations.

I do it again six months prior to the car going out of warranty.

Let hard data tell you what you need to know about what’s going in inside your engine.

Changed my oil cost me 32 bucks with 0-20W/filter and 20 mins, less if I wasn’t so old and my car wasn’t so low to ground.

You are not ones trying to reach it’s ones that never check oil level or wait for idiot “change engine oil soon” to light up to get to 10% That may take years? But, don’t matter anyway cause 99% of them lease or trade every two or three years.

Yup, I lost my first Ford Explorer to failure. Thing is, I should've "checked the oil" every couple of gas fill-ups. Because I didn't do that, and waited for the low oil light to go on, I didn't realize there was a problem. Turns out, I had holes. When they cleaned it up, the holes were unplugged, and the leakage became significant. Engine seized, had to replace the engine. A rebuild and the labor would've cost more than I paid for the vehicle, so I traded it in for another. Turned out THAT one was a lemon, and I sold it to some guy I worked for cheap just to get rid of it.

Did you read the Mobil one LIMITED warranty. After one year you’re on you own. Did you watch the video what Toyota mechanic had to say? Sure you leave in as long as you want as long as you know where dipstick is. IMO the problem arises when some go by oil indicators percentage and never check oil that keep vehicle over 6 or so years. That’s when lack of oil changes/checking starts coking process. Agree you can do nothing if you trade every few years. I bet there no oil manufacture recommendations longer than 1 year? Why cause oil start breaking down due to heat cycles. Sure you can oil tested but eventually that defeats cost oil change. Commercial trucking different, over road driving different. When vehicles takes gallons of oil cost effective to have it tested.

This was not started for people has has some knowledge on oil changes and internals and know where dip stick is. . It for one’s that go strictly by oil life cycle on dash which in my case could take 3 or more years of stop and go driving to reach recommended limit on oil life. Plus the oil manufacture don’t recommend longer than 1 year. If you check oil occasionally and trade within few years you will probably never experience VVT rattle or stuck piston rings cause it takes years of neglect to cause those problems.

This way a mechanic can give it a good onceover to help prevent problems and have noticed get well over 100,000 miles on the car.

Cheap insurance

When changing your oil, I would suggest using synthetic oil, even if the manufacturer doesn't require it. It doesn't cost much more, it is more durable, and you may end up spending less for oil changes long term because you can extend the time between changes.

If EVs take off eventually there will be repair centers for batteries which may cut cost in half or less of new pack. Time will tell if hydrogen engines don’t take over markets.

Recently, I got a synthetic oil change at Wildwood Tire for $78. They don't suggest another oil change for 10,000 miles, but I will probably do it after 7,500 miles, which will be about one year.

With millions of EVs on the road today and thousands of electric carts in the Villages and elsewhere, just what constitutes "taking off"? What will it take for the naysayers to accept that the boogeyman of battery-replacement cost is a non-starter?

Just use a MB 229.52 /Porsche C30 oil 5w30 every 2 years is fine. Zero sludge or shearing. Valvoline XL-III is a good one and is relatively cheap.

As a result, I change oil based on time.........not miles.
I change oil between 12 & 18 months.
Never had a problem.
Have dropped the oil pan to inspect.

I do stay away from Pennsylvania oil.

Creates sludge faster (than other oils) in engines.

Some say true, some say false.

And maybe they refine it better these days.

LOL, you might do the math on that one. A $69 oil change once a year x 10 years is $699 minimum. If you do more driving then it will be higher and don’t forget all the other “schedule maintenance” which may put you at that replacement battery cost. I heard for the Prius that is around $2K? I’m sure it’s more for a Tesla but how long do you actually keep your car anyhow?

You're right about synthetic oil. When I was working I was in outside sales and drove over 50k a year. I had a new Toyota Tacoma at that time. I always ran Mobil 1 synthetic and went 12000 on an oil change. At 200k miles I sold it and it still ran like new and used no oil.

Ever hear of an oil related failure? Here's my opinion on oil change interval. I think many spend a lot more than necessary on unneeded maintenance.

Today's engines along with current oil formulations easily tolerate even the worst abuse from extended use of oil. As long as there is sufficient oil in the crankcase you are unlikely to see any type of failure from not changing oil regularly. Nothing wrong with changing oil frequently if you want to spend the money on unnecessary maintenance, but even manufacturers recommendations have greatly increased time / milage. Every 3,000 miles or 6 months has increased to every 7,500 or 1 yr for non synthetic and much longer for synthetic.

read a very interesting repair mechanic's post about changing oil about 1 particular car: the owner never changed oil once in the greater than 5 years of ownership. Never once!

instead he just changed the filter every 2,000 miles and added oil.

The car was traded into the same dealership, the mechanic went to check inside the engine, and the engine had very little wear.

The most important point is using the best filter you can buy, as that is what keeps the oil clean in the engine and keeps the engine wear to a minimum. For low mileage driving, change the filter every 6 months and add oil.

On the very small coastwise tanker I worked for about 5 years, it had twin GM locomotive 2 stroke diesel engines. The oil was changed every three years in the shipyard. The oil was kept clean with a centrifuge oil cleaner and filters. not sure how often the filters were changed, but we had to be in port for a significant period of time in order to take an engine offline, as ships need to ready to leave the dock at any time. .

So don't go all oil change crazy when regular simple maintenance of the most important part of the lubrication system is required.

YMMV

Not possible to just change the filter without draining the oil if the filter is on the bottom.
