Observations of singular examples are not statistically significant. There are too many variables to use your own personal observations of even a handful of vehicles as evidence of any trend.I knew a guy, a courier. A full tank of gas every day !
Sometimes more, we made a chit ton of money.
90% heavy city traffic in the central Florida heat.
He changed his oil every 5,000 miles.
He let Jiffy Lube do it, the cheapest roach oil and the cheapest no name filter.
The filters were white and only a part number on them.
At 500,000 miles he traded it in on a new one.
Never had an engine problem,
Never used any synthetic blend or full syn.
500,000 miles ! He did it again with the next Four banger Tacoma.
I took one to 528,000 on full synthetic, Mobil 1
I did 10,000 mile oil change intervals.
Iin the Florida heat. Same heavy loading as my buddy.
Only diff was I was mostly on the interstates and often pulling a 2,000 enclosed trailer.
We always had 600 to 1200 pounds in the truck bed.
Compression was so low the vehicle was unsafe.
Now tell me again the advantage of full syn ?
I’d really like to know.
I use the Motorcraft blend .
