The radiator I have been to lazy to fix, the transmission was a product of to much line pressure in the programming. Both have been fixed.

Point of the info, almost 100K with zero core problems

Your point? I could just as easily say what kind of jackass would run a year without an oil change? I manage to maintain myself is the difference.

I fail to make the connection with your comment. Most obviously, synthetic oil doesn't turn black and into sludge, so the color stays the same. I would figure someone with your extensive knowledge would know this. Then again, you are running a miracle in a bottle oil, maybe it does turn black in a year.

Actually, the problem is that I am not ignorant enough to fall for such a marketing ploy as to believe that a miracle product that has been available for 25 years and hasn't yet achieved mainstream status, won't certify ALL of its products, and portrays itself much like a product called Prolong (snake oils for lack of a better term) I know that my engine is safe with the products that are its lifeblood. 25 years, and still hasn't gone mainstream. Thats proof enough for me.

 

use 5-20 10-30 10-40 dam oil is oil just change it evey 3-5,000 miles and and check it often, use a good filter.

 

Food for thought. If everyone just added 2000 miles to their oil change interval, how much oil would be saved over a one year period?

It depends, are we talking syn or dino? Syn doesn't really matter since man makes it. Doing it with dino, well, it'd be a hard number to estimate. You say add 2000 miles, but what are you adding it too? Maybe I change at 3K, and you change at 5K, and Joe changes at 7K. If you and I do it, we might save a little, but if joe does it over the life of his engine, a massive failure may cause more damage to his pocketbook than the savings in money and oil by the extension would be worth

 

oh please! a massive engine failure because of 5M or even 10M oil change intervals? not a chance. ran a 4 cyl VW for 250M miles with 7M oil change intervals. never used a drop of oil. Our Audi calls for 10M oil change intervals. Our BMW was 9M between changes. They've never used a drop of oil or had a moments problem. 3M oil change intervals waste money and natural resources. but it's a free world where anyone can do the equivalent of setting their money of fire.

 

What do they make it from?????

 

Exactly. 3K changes are a waste unless you do nothing but frequent short trips where your engine never reaches full operating temperature. You will than need to do it to remove condensable vapors etc.

 

if you had jiffy lube or whoever change your oil every 3k miles and you drive 15k a year that would be a cost of lets say $29 x 5 = $145.00 per year or $725 for 5 years of service. if you went to 5k changes it would be $87.00 per year or $435 for 5 years. so a savings of $290 over 5 years or $59 per year, if that is a lot of money to you then take the change and go to 5k changes. now if we all owned companies with a fleet of 100 truck, this would be different.

i am only being honest but, with a company to run, a wife and 2 kids, oil changes have become a chore, not a hobby. i get the oil changed when i have time somewhere between 3k and 4k miles. i suspect others are the same way and this why there is an oil change place on every corner. makes you wonder if someone set up a company that advertised, "get your oil changed once a year," charge the $145 price one time a year (or maybe a little more) with say a free check up every 3 months if this would be a money making venture. push it as a thing to free up more personal time.

 

I currently have 238k miles on my 98 F150 with a 302 V8 and my oil pressure is outstanding! It has no reduced power and it has been a reliable motor for me.
When I bought the truck in 91 I started using Schaffer in it. Folks from where I come from swear by Schaffer and have for decades. I wouldnt use anything else in anything with an engine that requires oil. These guys know oil better than most anybody and make an oil or lubricant for most any application, just take a peek at their website. http://www.schaefferoil.com/

Schaeffer is the oldest oil company in America and a leader in synthetic lubricants. I swear by their products and use many of them. I know there are some other good oills out there and wouldnt say anything bad about them but after reading all the stuff in this thread about other oils I just had to mention the oil "I" trust the most.

Also, On the subject of oil filters, The best filters out there cant filter out everything or they would restrict the flow too much adn thats why I use a Filtermag. I have used one for a long time and after cutting an old filter open after an oil change I would never not use one! Try for yourself and you might come to the same conclusion! http://www.filtermag.com/

And thats my two cents.

 

I have heard great things about Schaeffer as well.

 

Never heard of schaeffer myself.

And from the little discovery special I watched Norm, it basically said that man creates the synthetic by some super duper process but that it isn't able to be used in gasoline production.

 

But is still derived from Petroleum like Dino oil.
Synthetic is chemically constructed or "synthesized" versus standard oil extraction or refining.

Good book:

There is a link to download the free PDF copy or you can purchase it.

 

Thanks for the link. I am going to read it, but I briefly skimmed the bottom of that page and found a couple things I found peculiar.

I beg to differ here. I have no mechanical issues with my 5.4 I have no pressure problems, no knocking, no problems whatsoever. But, with synthetic oil installed I still burn between 1.5 and 2.5 quarts in a 3000 mile interval. The Nav isn't really driven all that hard for most of its operational time, like I said its my wifes. And I don't beat on it, although I drive it like I want. I'd like to hear how he could explain my case.

That last line provides some oddities (sp?) Depending on manufacturer depends on what mileage is recommended, but more importantly in a car that is under warranty (this is meant for more or less newer vehicles) they can tell how many times you're oil light has been reset. (you'd be amazed how much data that computer retains) So if you ended up with an oil related issue while in the warranty period, and you're car tells them the lights been reset 10 times, but you can only prove that its been done 5 times, you'll get screwed out of your warranty because you followed the oil manufacturers instructions instead of the automobile manufacturers instructions. I am not specifying any particular oil either. I'd be hard pressed to try and save myself a $100 bucks a year in oil on the $40K truck everyone keeps talking about pampering with name brand expensive stuff but wants to cheap out and change the oil every 10K miles by taking my warranty out of the Fords hands and putting it into Mobil, amsoil, valvoline, or pennzoils hands based on a chitty guarantee that has a ton of loop holes and *'s right there on the side of the box. (dam, that was a long sentence)

But I'll read the rest of it tonight later on. Thanks
