And there are many more people just like you with the same results.

 

So I read the boboilguy thread on oil analysis. Thats great. Check for metals, alkalinity, acidity, and so forth. (A spectrometer is an instrument with which one can measure the quantities and types of metallic elements in a sample of oil.) What it doesn't check is that greasy sludge buildup thats in the botton of your pan and throughout the oil channels and in the valvetrain. Analyze that one time and tell me how good that is for your valvetrain components. Of course, you could prevent it ever happening by changing it before it turns to sludge, but then that would mean like the product manufacturer says at 3000 miles, but don't trust them they just want to sell oil.

Thats from your last citing webpage. It concurs exactly with what I am saying. The cost of an oil change is so low, that the cost of an analysis outwieghs any benefit you might get from it. If you do an analysis that says your oil is good for another 3000 miles at 3000 run, then you just spent half or more the cost of that oil change to find out you didn't need it. Wasting more money and time than you would have had you just changed it.

Extended intervals also cause the following, another exert from your source

Also, that entire article is based around machinary other than auto's. Those type mechanisms also run the same speed in controlled conditions will little to no addition in stress from factors like those in automotive conditions. In all truth, that article had nothing to do with automobiles and is irrelevant to this discussion in my opinion. It would be like me citing a gokart motor change interval

 

And oh yeah, there are many people like that with new motors too!

Could you also answer the question that I have asked several times throughout the several oil threads that everyone avoids like the plauge?

Why did Toyota, while recommending 7500 mile oil changes, have so many problems with oil gelling and replace so many motors that were not under warranty?

 

Again you are wrong. I'm done. You win. Every one bow down to the self proclaimed expert and change your oil when he says even if it still has 3-5K or more miles of life in it.

I am not a Toyota expert so I can't answer that question.

I am done with you.

There comes a point in an argument where it is just going on for the sake of argument and it is counter-productive. We have passed that point.
Even when presented with facts and real world experiences you will not change your mind and that is fine. It is your truck do what you like. You clearly make good money at your shop changing everyones oil at 3000 miles whether they need it or not. More power to you. Hope you and your oil distrubutor continue to get rich.

If you do not feel comfortable with proven extended intervals don't use them. Quite simple. I know they work as do others that have posted here. I will continue to use them. I have over 82K miles and both of my Ford warranties have expired. I have absolutely no engine problems just like the many others that have posted their results in this thread an others.

I am over 40 and have no wish to continue trying to enlighten you. I work with Mass Spectroscopy everyday. I know what they can do.
If you want your sludge tested send Blackstone a sample. My engine has no sludge even with my once a year oil changes. My wife's Focus has no sludge either.

Best of luck to you. I will not be back to this thread unless my engine fails and proves you right. Not likely.

 

For those who understand no explanation is necessary, for those who don’t none is possible.

 

Why do BMW and Porsche recommend 15,000 miles? Why does Honda recommend 10,000 miles (dino oil)? Both these companies are renowned engine makers and all 3 are known for very durable engines.

 

I'm at about 6400 miles on Amsoil 5-30 on a Honda Civic with 78K and NO lock up. Previous Amsoil had 10K when I changed it. Miracle product no....good company in business for 25+-years, yes!

The quick lube guy will looooooose a ton of business if we were to extend our oil changes out past 3k and the oil companies who's articles he linked would stand to loose alot more.....like I said it is not in his best interest to suggest extended oil change intervals based on quality oil/filters with analysis. Everyone must research and decide for themselves. Do not listen to me or the Jiffy Lube guy, but gather all the information you can and decide what is best for you.

I have yet to see any sludge build up inside my valve covers on the Honda or my previous truck an F250 PSD.....both using Amsoil filter and oil with analysis from Oilgaurd. Oil pan sludge is also not an issue.....what the hell are ya talking about

"If its such a great product, then why don't any manufacturers carry it from day one? Why isn't it a shelved product at your local parts store?"

That's easy.....Oil producer/refiners are probably the most powerful industries in this country! Petrochemicals drive our economy......you name it it's made or has some relationship with oil or it's by-products. True synthetic oils like Mobil, Amsoil, Redline are not produced from crude. Mobil has the advantage of being a product of a MAJOR oil company so their marketing power is above all the rest in the synthetic market. That explains their synthetic product being the only factory fill.....Corvette, Viper. Amsoil uses MOBIL synthetic stocks. The only difference between the two products is the additive package....Amsoil uses additives from a company called Lubrizoil. Lubrizoil produces this package according to Amsoil specs and Amsoils requirement to market products for extended drain intervals. I could go on but I'm getting bored. Anyone who has a question about synthetics and there possible use can find the information using Google or this site.

 

Ihear a bunch of crap I'd expect to hear from someone like John Kerry on your resonses.

I have given you the data I have every month. I have shown you that at 5000 miles a majority of people are low on oil. AM I getting rich, hell no. There is little profit in an oil change, even at $30. If I was getting rich, I wouldn't be looking for advice in a forum since I am a DIYer. I'd be paying someone to to the work for me.

How do you know there is no buildup in your pan? Have you removed it lately and checked to see?

And, for the umtamillionth time, synthetics don't create buildup. Do you guys even read these post? AMsoil is a synthetic. (one of which I would poor in my deep fryer) It will not create sludge, it will cause premature wear. You won't see that wear until it breaks because its internal components.

If thats true, then explain why Mobil 1 synthetic is factory used and recommended by Mercedes Benz, Chevy Corevettes, and other high performance models? You can't. Mobil 1 isn't a miracle product, its an oil thats been around for years and years and years. They just came out with their Extended products, and have enough exlusions on the back to all but exclude use in cars for that mile frame. I have read the bottle, I sell the oil (not the extended version, but people do brind their own oil)

I think enough people have agreed that paying $19 (or whatever the cost) outwieghs the benefit. LIke I already said, paying $19 to find out you can supposedly go another 3000 does you no good, your just saving $6 to use older more worn lubricants instead of just changing to new.

And BMW may haave a longer interval (i;d like to know where this 15000 mark came from, since BMW has never released a mileage figure, they rely on the lights) but that doesn't mean that the owners of those cars follow it. I had a 92 325i and it was at 3000 everytime. I have BMW owners whose cars have free maintenence, and they change their oil on their dime in between to make sure their investment is protected. And never once in all my years has anyone ever asked me for a sample to have analyzed, its just not necassary

 

John Kerry.....what! You right-wing jackazz. Learn how to spell and maybe your points will be taken seriously!

"If thats true, then explain why Mobil 1 synthetic is factory used and recommended by Mercedes Benz, Chevy Corevettes, and other high performance models? You can't."

Like I said, Mobil has the marketing power that the others don't. Amsoil V. Mobil.....not hard too figure out who wins Like I said before Amsoil uses Mobil One base stock and Lubrizoil additives so one can expect the performance of Mobil one and the extended drain interval promissed by Amsoil.

Majority of people low on oil at 5K I have had 20 plus vehicles from new to 70K and have never had a vehicle consume 1qt of oil during the recomended oil drain interval.

"You won't see that wear until it breaks because its internal components"

What???? Oil Analysis will show wear materials in oil! Internal wear is what analysis is all about.

"And never once in all my years has anyone ever asked me for a sample to have analyzed, its just not necassary"

No it's not necessary. If someone changes their oil within 5K Why would they need analysis? After 5K analysis is needed....it lets you know how long the oil is good for.
