switching from regular to synthetic oil
#11
Doing extended drain intervals safely is all about oil analysis. Since the oil analysis is additional time and money, it may not be worth the additional trouble every time. However, once you get to 10k miles on a interval and the analysis tells you that you are fine, you can safely use that interval for the next few oil changes without having to do more analysii...thus saving oil, time and money.

FWIW, my father uses syn in his 05 and he had plug fouling at 32000km's and the other day I noticed a cloud of blue smoke after startup and he is at 65000kms. He also ran syn in a 2000GMC with 8.1L(?) and also had plug fouling problems.

You are WRONG!!!!!! Any oil will sludge up an engine if not changed properly. We see them come in the shop ALL the time because the engine is sludged up. These cars require synthetic from the factory. Mercedes says Mobil 1, BMW uses Castroil and VW uses Castroil. Mercedes oil changes are 10k oil changes VW switched from 10k to 5k because of sludge and bmw has a 12k oil change interval. We are seeing ALOT sludge issues with the ones that do the oil changes every 10 k or more. I have something better than education. Its called real life.
You said it yourself in your first sentence I've been saying an interval of 10K with filter change at 5K. That's a proper way and NOT a ridiculously long time!! And regular too!! No need to get your panties in a bunch, I've been dealing with much higher dollar motors than what's in yours or my truck for years. You certainly may go much longer than what has been stated when using a good by-pass system too!!!. The additive pkg. in today's Syns are extremely superior than ever before. Dino is also superior today than ever before. We are both entitled to our opinions and if you research more, you will understand better. Education??? Priceless!!! Real life experience dictates otherwise. Be lucky you live in a climate where people don't maintain their vehicles, because this is obviously helping you stay in business. We should just just agree to disagree and have a cold one, on me!
Floriduh vehicles probably should go on an extreme duty cycle for maintenance just due to climate alone. High humidity isn't that great for anything for any extended period of time. If anyone is fouling plugs on a lower mile engine, I would seriously look at the problem from a manufacturing tolerance stand point at the factory rather than the oil
IMO, Amsoil and Mobil 1 probably have the best additive pkg. out there. I'm using Mobil 1 in this F150. At present in my Dodge Cummins, I use Mobil Delvac 1300 super, by far the only dino out there with the best pkg. for diesel application!l not a SYN, cause I need to use up the 5 cases I have laying around! Then it's it's Mobil 1..

If I had plugs fouling at 32,000 or blue oil smoke at 65,000 I'd be choking someone at Ford. I had a '97 Explorer 4.0L (80,000) that used nothing but Castrol Syntec and Fram. The day I got rid of it, start up didn't even show water vapor let alone and sign of ring blow-by or any indication a need for a valve job. It may have sounded like a diesel with the last rod bearing slapping around, but thats another story...hahaha!

Blue smoke may have been caused from a bad valve seat. I had that problem in my 02 I believe it started doing that somewhere around 30K. The fouled plug is another problem I had it happen at 47K, plug #3. It's also a common problem. These problems have nothing to do with the oil used.

No I said oil change every 5k not just a filter. As far as engines worth more than whats in my truck yes that might be true, but the last engine I priced out due to sludge was 40k in an E55. That sounds pretty pricey to me. The customer followed MB oil change interval and ran nothing but mobil 1. I saw his maintenance book myself and every service was done. He is VERY particular about that car. MB is buying the motor for him and installing it at a dealer. The reason I said you are wrong is you said synthetic does not sludge up. It does. That's real life. I don't care what the synthetic ppl claim. I have seen diffrent. So real live owns education at that point. I still have to say again over a 200,000 mile period synthetics cost an average of 2000 dollars more than regular oil at 5 k intervals to change. Why risk your second most expensive investment over a measly 2k?????
Hear say!! Doesnt matter what you saw from the customers maintenance record, he can write and say anything he wanted to!!
Going 10K miles on a Syn oil before changing is not a long period of time!!!!! Some will say your wasting perfectly good oil!! I still have some old school in me so this is why I only go to 10K. Filtration is a KEY ingredient here! Neglect will ruin anything, I don't care how good or expensive any part is!! Just change that filter every 5K and oil w/filter at 10, then your good to for the life of that motor! That's my story and I'm sticking to it!
The last hi-pro 5.0, with a Paxton blower on it I had, showed NO signs, what so ever, or any suggestion of sludge at tear down!! Matter of fact, is was clean as a whistle with no signs of any suggested anything internally! Coating properties, lubricating abilities wear and oil longevity factor, are just plain and simple SUPERIOR, over any dino! That's just a plain and simple fact, so I hope there was some real life education absorbed her. Take another look at the two posts below your last one, Whitecrystal and Monty F150x4 have a little insight. You are entitled to do and believe what you wish, I will stick with what I know and live from experience. This doesn't really make you nor I wrong, just different beliefs..

He didn't fake the stamps we put in it. I seriously doubt he faked the dealer stamps considering there were 3 diffrent dealer stamps in the book.

The oil's lubrication properties and detergents break down. Filtration is NOT going to stop that.
The last hi-pro <<<WTF is that Ford has not made a (im sure you meant hi-po) motor in 35 years. 5.0, with a Paxton blower on it I had, showed NO signs, what so ever, or any suggestion of sludge at tear down!!

You are continuing to over exaggerate the situation. NO ONE is going umteen zillion miles on a change Maybe, that in it self is the problems with your customers and maybe you should educate them!! I used to go 3K on my gas rigs and diesels too. That was a waste of $$ and oil because to days additive pkgs are once again superior and start really working between 2-3K miles, so why waste good oil?? Once again, 10K with 5K filters is perfectly fine!!!! Matter of fact, at 10K the oil is still in excellent protective mode sort of speak!
