why is maintenance schedule different from each dealer?

OH, I care. I like learning even at 67. I made a statement once if Toyota and Honda say it, it’s true. OH BS. Grumpy schooled me. Honda and Toyota realized that most Honda owners are done at 150K miles and gear maintenance schedule according to that. Long life tune ups and fluids. My daughters Odyssey is a good example. It was still moving at 120K. But it needed serious maintenance all at once to survive another 80k. They could have shorten some maintenance services for longevity. Doing that would raise the cost for normal maintenance. Unless you’re just driving the interstate in some cases the severe maintenance schedule is a must. My wife’s oil in the Genesis at 4K miles looks just changed. The odyssey looks like it’s burnt. The difference is the maintenance schedule.

I would strongly disagree.  I knew nothing about the current subject matter and I have now been educated.  Good, bad, or otherwise, I now know more than I did before reading it and I am of greater value for it.  

 

As mentioned above in someone else's post, I am unsure whether the original topic was intended for discussion or confirmation.  If posted for confirmation, then that would lead me to believe the post was made with an expectation bias, often resulting in confirmation bias, which most often results in a complete dismantling of any attempt to validate results using the scientific method. 

 

Hopefully the intent of the post was a true inquiry and the resulting tangents being discussed have benefited people.  I know I have gained knowledge from them and therefore appreciate the posted discussions.

I had an enlightened experience today regarding the Genesis oil change. It’s been a dealer only experience with this car driven by the warranty period. Today like usual I showed up for its oil change. They asked if I had an appointment. The first time in about 30 years of using this GMC-Hyundai dealership. I’ve been getting disillusion with this dealership since they wouldn’t inspect my avalanche with foggy headlights. I went down the road to a valvoline quick change-inspection service. An independent owned shop. Two years in a row I’ve been getting hassle free quick inspections. Down there I go, screw the dealership. Appointment my a$$. Impressed I am. They pulled the air filter out and showed me. The used TQ wrench’s on all tightening. Being the filter was on top I could see the procedure while in the car. The manager overseeing the whole procedure while shouting out every completion. And they show the clean full oil on the dipstick. I was impressed. Not just for inspection anymore. In and out in a half of an hour. 

It was time for the odysseys inspection. So yesterday I went back to this place. Got her done. Then the person says if need an oil change half price today only. So at 4K miles on this oil got it done. I’m loving this place. Avalanche next, soon.

What mowing a lawn teaches us about changing our oil 

 

Hired a lawn service. Correction, wife hired a lawn service. Happy as a clam she did. I really needed the help. 

 

Guy gave me a lawn measure. A ruler with some hints and tips on mowing. One of those tips was you should never cut more than 1/3 of the blade length in a mowing. It also suggested the minimum 'healthy' just mowed height is 3 inches. 4.5" is the maximum height I should let it get to maintain a 3" groomed length. 

 

Okay, so how long does it take to grow 1.5"? It's the same question as, "How long should I leave oil in the motor. The transmission. The differential. 

 

In the wet of spring after fertilization I may mow every other day. I the dry of late fall, perhaps once every 10-15 days. Winter? 4 to 5 months. 

 

What do I need to know to decide when it's time?

Could he be on to something?  

 

Dizzy has been that teaching Nun with the steel-edged rule that keeps whacking your hands when you error and remains silent when you don't, and you are just afraid to look up. Eventually you get the idea that the better the motor is running and the more favorable the operating/environmental conditions are; the longer that oil 'looks", smells and feels new. 

 

Hot bread wastes your money. Your motor favors toast and isn't favored any more by hot bread. The API and the OEM test for the edge of furious. Your lab favors NO! The OEM and the EPA favor your failure to tell the difference. 

 

 

Each entity calls it quits when it is most profitable for THEM, not your motor.

Here is a life hack OP in regard to maintenance. If you change it to Amsoil, you never have to change any of your fluids again. The up-front costs are all savings after the third oil change as they are lifetime fluid... Now you will be required to attend their yearly company outing to celebrate the top sales leaders and go in for a presentation prior to purchase (similar to a timeshare), but one and done. Well worth it!

Did you get out of the wrong side of the bed? Instead of being condescending how about giving real life personal experiences? There’s two ways to interpret your statement depending on your experience level. To a novice very confusing and of no help. I’ve actually had done just that with the exception of oil. And did 25K oil changes successfully in certain targeted vehicles. And being an early Amsoil dealer and OEM with John Deer, Cat among others in the past. Never got invited to a company event. And having a son who made a good living selling timeshare out of high school for 15 years. I don’t see the connection.

That is nonsense.  Dealers are NOT required to attend any meeting or presentation of any kind.   Made up bs.

I use it when it fits my application but I see the humor. Amsoil definitely does have a cult-like following, and I’ve seen blind faith and ridiculous claims from it’s fans over the years. Was talking to a guy who just did Amsoil in his truck’s transmission (and everywhere else). He swears it fixed a driveline clunk that’s been proven by the manufacturer to come from the driveshaft’s slip yoke (tight tolerances binding the splines in warm weather). Mind you, this is a slip yoke that is bolted to a flange off the back of the transfer case and not exposed to any lubricant. Must be damn good stuff!

Track Day guys goes out and beats up his car for a few hours. Then goes home and changes his oil. But he will run in for 20K miles in that same car when driving it 5 miles one way to work 5 days a week.

I can say I’ve seen hydraulic pumps and motors on my and customers equipment survive hoses failing cavitation using Amsoil. Where regular hydraulic oils couldn’t and didn’t protect the pumps and motors. Causing thousands in repairs. I saw transmissions in our heavy use 1 ton trucks fail at 100K miles with normal transmission fluid. Not fail once changed to Amsoil. Early on switching to Amsoil from conventional oil in heavy equipment seeing a drop in working temperature and steadier oil pressure. It’s definitely possible everyone has caught up. Amsoil was first to be better I’ve witnessed the results in hundreds of equipment and cars and trucks. I don’t use it in all my stuff anymore because I don’t do all my own vehicles anymore. It’s in my old 02 avalanche and she’s still original. People who care about their rides probably use it at least in their transmission and rear ends. If I was still driving my truck 50k miles a year on the highway I’d definitely be using it.

I have Red Line in my engine and diffs. Went back with fresh OEM fluid in the transfer case after break-in. And trans is still factory fill. Unfortunately not as easy as just dropping the pan and refilling from the dipstick tube so I’ll address it at a later date. Maybe that’s why they say it’s “lubed for life”.

 

I still run Amsoil Euro in my wife’s car (she beats the hell out of it) and their small engine oil in my tractor (I beat the hell out of it). Used their marine stuff in my Honda outboard for a few years before concluding it was a waste of money. I change it too frequently to address fuel dilution from trolling. So Farm & Fleet conventional oil is the ticket. Buy on sale by the case and costs me a third (or less) what Amsoil did. If there’s a difference in the motor one way or the other between those oils it probably can’t be measured in that usage case.

The only boutique oils I run are Redline Heavy Shockproof gear oil in my HD's transmission and the same in my snowmobile chain cases. In those cases, there is a difference in performance, less wear in the sled chain cases, etc. as that stuff is way more robust than the OEM recommended oils. 

The price of these boutique oils is not worth it for motor oils. Brand name full synth. oils are just fine. I prefer API certified oils not qualified ones.

Back to the OP first post.

 

People like money more than just about anything else. The guy that sells oil or oil changes wants more oil changes. The guy who sells cars wants to sell more cars. The guy who sells oil condition services wants you dependent on his services. The consumer wants what's cheap and convenient and effortless. The government wants votes, and the EPA wants to be needed. 

 

Now you need a car, so you will buy one. It needs an oil change, so it gets one. Maybe you use a monitoring service, so he gets his. The government and the EPA get theirs no matter what. Consumer falls into the trap of cheap easy and convenient as a way to satisfy everyone but mostly himself. 

 

What got ignored in satisfying all those needy little baby birds clamoring for the worm? 

 

How about what the driveline needed?

Run Shockproof Heavy in my HD as well. Red Line MTL made a huge difference in my 98 Honda HX transmission shift quality. I run a cooler and Red Line HP 10W40 in that twin cam 88 as well, with a cooler. Every case was a difference that could be felt. 

 

Red Line has 'friction packages' figured out. I've posted graphs of Peppers oil temp profile using various oils before. I've found nothing to date that runs cooler than Red Line HP and the difference is pronounced.
