I’ve replaced the lithium batteries on my cordless tools several times. After so many charging cycles one day they work and next day they don’t. When charging Computer Circuit in lithium battery pack cut them off at about 1/3 discharge. How do I know this? I check it several times with multimeter when battery was discharged. Example 56V battery pack shut off at about 41Vs.

Admit it you traded it cause you knew if was going to cost you big time. I drove Ford Torino for 180K miles and 8 years. When I sold it didn’t use any oil between changes. In those 8 years I changed water pump, brakes, heater hoses, tires. The kid I sold it to drove it for another 4 years going to collage. Not bad for his 1100 dollar investment.

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.

If you use motorcraft brand it’s most likely synthetic blended if in red container? Blended is not full synthetic oil.

I went to Wildwood Tire and asked for full synthetic oil, not blended. The receipt says "full synthetic oil package (5 qt)", $69.95. If they substituted something else, then I have no way to know what I got.

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.

Porsche has oil refineries?

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.

Just curious, what is wrong with Pennsylvania oil?

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?

Creates sludge faster (than other oils) in engines.

Some say true, some say false.

And maybe they refine it better these days.

Old penzoil formula 40 plus years ago would foam also. Had friend that used old formula and rarely changed oil. Had SBC and lifter rattle problems. When I took valve covers off I could not see one lifter due to slugging and coking buildup. Penzoil now nowhere near the old formula. Another thing older vehicles with primitive PVC systems and old formulated oils would not reduce internal condensation which in winter months would Cassie oil to get diluted and look milky.

I don’t care

12K internals That was 3 oil changes in year on down road driving which puts around 80 to 90% or less wear on engine so, your Toyota actually had less than 100K wear on engine. Probably closer to 60K with oil change internals. Extreme conditions like start and go, stop and go driving, pulling heavy loads, or extreme dusty conditions like in desert states require different oil change internals. Not me saying this it’s the industry.

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.

My understanding is that oil chemistry has increased the life of engine oil the biggest factor is the electronic engine controls burns the fuel so much better/cleaner the oil gets much less contaminated / dirty

[Shipping up to Boston]

Remember the Slant 6 engine (Dodge/Chrysler)?
So durable and indestructible it would run with no oil....or pancake syrup!

I'm a very experianced car and motorcycle guy. The truth is IF you have a high quality car (toyota, Honda etc) and change the oil every 2,000 miles it will last forever.


Oh course if you have the same car and beat the hell out of it and change the oil only at the manufactures recomended mileage....your car will last forever...but I must admit there is something cathartic about changing way before it is really needed.
