Except for all the 'oily' waste generated.... oil filters, oil containers, oily rags, the potential for spills and .....the oil itself.

More proof that the 3000 mile change is bogus

Yeah, no kidding. "Fortunately" he trades cars pretty often, so there probably isn't much damage done...but makes me think why bother changing every 3K if you're going to get rid of it in 3 years
Coolant at every oil change? I hope that's not like 3-4X a year...
I disagree here. I don't see a need to run premium in a car not requiring it. The biggest difference in fuel grades is the octane. There may be some addative difference in some stores, but not enough to merrit the 20+ cent difference. Shell says they use the same addative levels in all grades. If it requires premium than that's another issue.

(1) It says "nearly all"
(2) If you listen to a Jiffy Lube commercial, they define severe as stop-n-go, high speed, or hot weather.
(3) In reality, only the stop-n-go would be severe. The high speed and/or hot weather has no impact and is defined as "normal"-7500-mile changes in car manuals.
(4) Conclusion: Jiffy Lube is spreading lies to make every one think they are driving their cars severely.
(5) #4 is not surprising. Jiffy Lube will do whatever it takes to put more money in their pockets. They can't break the laws, but they can redefine everyone as a "severe driver" through ads & lying.

I have never seen evidence that a vehicle which calls for regular fuel will return higher fuel economy with premium fuel. I have seen the opposite, that vehicles which call for premium fuel sometimes give worse fuel economy and performance on substandard octane fuel.
In California at least, all fuels are required by law to carry a goodly amount of detergents. In some other states it *might* still be the case that higher grades of fuel have more detergents, but I have not seen an documentation which proves it.
Generally speaking, running premium fuel in a vehicle which specifies regular fuel is a waste of money.

Lots of good, science and analysis-based evidence on this site that 3K oil changes are unnecessary for the great majority of drivers.
On a more acecdotal point, we know that oils of today are greatly superior to the lubes of 1966. Yet the 1966 Chrysler Imperial required 4K oil changes for warranty purposes (I recently linked to a vintage ad for that car which addressed this issue). To think that somehow powerplant design, machining capabilities, materials engineering, and petrochemistry somehow haven't progressed substantially beyond what was available in 1966 -- that concept's a joke to me.
Excepting truly Severe Service, 3K oil changes are a great idea and good practice...if you happen to own a Jiffy Lube franchise.

Something to think about.
Guy in a class at school(works at Kwik Kar, drives a 5.0 mustang, thinks he is master mechanic) just told me Kwik Kar sent him off to lube tech school. Says they taught him at school that synthetic oil cannot go longer than 3000 miles and is a myth. When I asked him why double the price he said it makes your engine last longer.
Oh, and everyone should have their engines flushed every third oil change despite maintenance intervals. His comment there, all the old oil never completely drains out and will cause build up. But what about the flush that doesn't drain completely out? He didn't say...

Yeah Patman runs oil for 2 minutes and drains it.
