Several of my friends have had oil pans rust out from the inside.this concerns me because my PSD requires a engine pull to replace the pan,we live with one of the oldest refiners in canada(sarnia) and have as a result the highest level of sulfer in our fuels,would sulfuric acids in the oil cause this and do extended drain intervals contribute?

Only true Luddites are still using 3000 mile oil changes and they're probably living in caves and hunting with sharp sticks ... [Wink]

Well there are a ton of em at my work and that I meet everyday, but I don't disagree, I think they all live in caves too.

And to top it off Ferd used the cheapest- cr**iest, pot metal oil pans they could find on these trucks. Watch that pan! several have shown rust on the outside. With that high sulfer, I would think look in Stinkys post for the oil with the most of all the additives you can find, highest Ca, highest TBN, maybe add some of that synpower oil treat to it, ad get it nice and hot regularly, then don't worry about doing anything less than 5 or 6000 miles between oil changes. PS. hint on te oil to use, Rotella T ain't it. Maybe if you can get it, run some Mystik JT-8 in there too.

Edit: sorry I guess the pan came from IH. but they are known to have issues.

You are right on both counts,my friends cars are Tarus and a windstar(could be the same engine) but mine is a international but I suspect the pan is ford or ford spec

Understand this is IMHO [Smile] ; Here I was talking about the Rot T regular 15-40, I personally feel that the add packs are not as good, the base oil is just ok, and in Canada I ahve seen some of the TBN's in the other Shell HDDO's are at about 9. Add to that that in his engine, I think this is sheared down by 4000 mi. So compared to the competition the dino R-T is my 3rd or 4th choice, and since he has high sulfur fuel, I think he should go with a more robust additive package oil that starts with better base oils to boot. Now I do not hold the same reservations about the Rot T GIII syn. I think it is about a 50% better oil than the GII competition, and about 100% better than Shells own dino, and it is priced at just that point as well, being about 50% more in cost currently than the competition.

The 3000 mile oil change will never go away as long as there are people that make a living out of changing and throwing away good oil. What ****** me off is the quick lubs that tell customers that the rear end oil has to be changed, and drain out synthetic gear lube and replace it with Hypoid oil. These are the guys that show you a sample of it with bubbles in it and tell you it has lost its anti-foam properties and needs to be changed right now. You should seen the look on their faces when I said "screw it, its a company car let it break."

Leave the writing of insurance policies to the trained actuaries, and the motor oil changing recommendations to the engineers who actually design the engines. Each are masters of their own domains.

I agree save the money and oil.

It's been obsolete for over a decade. Some people never learn I guess?

I guess I am really stupid for following what owner's manual for my last 2 cars reccomends. If I had half a brain, I would go back to the longer intervals that gave me sludge before them.

Nope thats the point, use the owners manual interval, GMC says to change the engine oil when the light comes on. The dealer wants me to change it at 3000 miles.

The last time it was in the dealer at 30K they changed the differential oil, drained out good synthetic and replaced at a cost of 144 dollars. I'm now in the process of getting a refund from them, they claim the chack is in the mail, time will tell.

In town either of our cars are getting about 20 mpg. In 5000 miles I've used 1000 quarts of gas at a cost of about $625. I just picked up a case of Havoline at less than $1 a quart, Purolator oil filters are $2.50 to $4.00 each, for an oil change cost 30 minutes and about $8 if I'm not using any synthetic. If I change my oil at 3k miles I'm using an extra five quarts and another $8. As I recall the severe duty change interval is 3k miles. But, for some reason, one is supposed to feel guilty about using 0.5% more oil products in an effort to get as many miles as possible out of a vehicle, when one could save 50% to 100% by buying and driving more fuel efficient vehicles.

By driving whatever vehicle you have you've already determined the biggest factor, by far, in oil consumption. Keep it in good condition by changing the oil whenever it needs it, and if you really want to make a statement buy a different vehicle if you're worried about using too much oil.

A late thought, some of the uoa's are between 3,000 to 4,000 miles.

Come to think of it, my dad's '81 Fiat 125 with 1.5 liter gasoline engine was on 20K km (12K miles) OCI, and all they used in it was dino oil (no one here even heard of synthetic oil back then). What were they thinking??? By the time it hit 100K km, it needed to be rebuilt. [freaknout] [crushedcar]
