Thanks Bich, I appreciate your input. BUT, I was referring to THIS thread titled "Oil Change Stuff" No need for me to read the sticky.
Thanks again,

I would seriously consider even going 7500 miles between oil changes instead of every 5k. But then when I sell the car I'll have to convince the buyer that more than 5k is okay? I just think the manufacturer, has brainwashed everyone into thinking 5k is the MAXIMUM a car should be driven between changes without causing damage...

 

I'm currently running the Amsoil dual bypass on my V8 4Runner and have 17K miles on Amsoil 0w-30 oil with Amsoil Ea nano-fiber filters. I have to change the full flow filter once a year and the bypass filter every 50K miles. I've been sending samples every 12.5K miles and everything is great.

Hardly. There are plenty of manufacturers that have longer change intervals... Subaru comes to mind, as does VW. Most newer BMW's and Mini's are up around 10k miles for oil changes. Porsche has an insane oil change interval of something like 20k miles.

The problem is with American manufacturers and oil company ad campaigns, that continue to push 3000 mile "servere driving" oil changes in this country.

 

Amen brother! It's such a waste of people's money and a waste of a non-renewable energy resource. I'm glad I'm not the only one on this forum that realizes the oil companies agenda for premature oil changes and that the manufacturers recommendations are not necessarily with the consumer's best interest in mind but more for their own pockets and their dealer's pockets. It's good to see others (koz, lobux, bichon, you, etc.) on here realize that going 10k between oil changes will not necessarily result in your engine dying...

 

I do almost all highway driving and put 5000k on my car every 6-8 weeks.---yes, over 40k miles a year. All my driving is right around 3k RPM, so I'm not taxing the engine at all. I think after the first 2 oil changes that I'm going to change my interval to 8-10k. Not for the $60 oil change, but time.

We had a 02' VW with a Turbo and it's interval was 10k miles??? Having a Turbo I would think would be alot more strain on an engine.

I agree that it's all marketing by the Oil Companies. I will expect my engine to start burning some oil when it's over 100k, so that will require me checking the level frequently.

My $.02

 

I agree that 3k is too little - BMW covers maintenance on their vehicles so the extended oil changes are to be expected. Porsche vehicles generally have about 10 quarts of oil, so 20k is to be expected from those vehicles.

On the IS, I'd probably recommend changes at about 10k (which I'll be doing as soon as my warranty is out).

Will you do every 5k before your warranty is up? Why not every 10k now? Worried about them voiding warranty?

 

I'm curious which VW turbo that was. I was under the impression that all of them had 1.8T or TDI had 5k mi intervals. At least it says so on VW's maintenance sched. I also had a VW turbo as well.

 

(I use $8k as the hypothetical amount it would cost to install a new engine in the IS. (Parts/Labor))

Unlike some people in the thread, I don't have an extra $8k in my pocket in the unlikely event that my engine fails due to a lubrication issue.

Something as simple as having the oil pump fail would cause the engine to seize. I would expect nothing less of a car manufacturer than to investigate every possible reason as to why it occured (including exceeding the recommended oil change interval). They could very likely determine an approximate change interval based on their own used oil analysis, and use it as a basis for denying a claim.

Personally, I don't mind the dealer, and $90 every 6 months is not a big deal for me. $8k is a big deal for me. Someone else in the thread said it best when they called it "Peace of mind".

-Brian

 

Well put Brian,
I was the one who mentioned "Peach of Mind". I have never had any problems selling any of my previous cars. I did not even have to put them on the market. I have a reputation of taking care of all my cars. I guess its like this, would you rather buy a car that you know was taken cared of, had all the services done on the car like clockwork. Or would you buy a car that when you lift the dipstick, its got all this varnish on it. That, by the way, is one of the tell taill signs that the services were not performed. So its not just my peace of mind, its also the potential buyer if I decide to sell the car later on.
Btw,I don't worry about using a non-renewable energy resource, because I use full sythetic Mobile 1.

Then you've obviously got no clue, given the fact that ALL synthetics are made from crude base stock.

 

I'm glad you could add something constructive to this thread. Given that you only have 143 posts and have only been on this forum for three months, maybe you should just keep your trap shut untill you learn some humility and can practice some mature etiquette. You don't even know who I am. I'm open to some constructive critizism, but not the inept rant you just displayed. Btw, its not " Then you've obviously got no clue", but should be "Then, you obviously have no clue" At least get the grammar correct.
Mods, Please close this thread if this crap persists!!

 

Not so!

Conventional petroleum basestocks or mineral oils begin with crude oil, a mixture of literally hundreds of different molecules. First they must be cleaned up; undesirable components such as waxes, unsaturated hydrocarbons, nitrogen and sulfur compounds must be removed. Modern processing techniques are good enough for well over 95% of the world's lubricant applications, but they cannot remove all of the bad actors. These inherent weaknesses limit the temperature range in which mineral oils can be used and shorten the useful life of the finished lubricant.

Synthetic basestocks, on the other hand, start from relatively pure and simple chemical building blocks which are synthesized into new, larger molecules. The synthetic basestock consists only of the pre-selected molecules and has no undesirable weak links that inhibit performance. The ability to pre-select or design specific ideal molecules tailored for a given job, and then creates those molecules and only those molecules. In fact, the entire formulation approach is different: instead of trying to clean up a naturally occurring chemical soup to acceptable levels, the synthetic molecular engineer is able to focus on optimum performance in a specific application with the knowledge that he can build the necessary molecules to achieve it.
