Nice example Bear. Although you used Gear oil for your example, we could easily substitute 0W30 in an engine that calls for 5W20, with no other options. I get the point. It would be a long drawn out uphill battle.

Stick to approved fluids, and mfg recommended intervals, in the suggested grade, and don't play games while under a warranty. Sound advice, and exactly what the service writer told us when we had my GF's Jeep in for a warranty issue. He flat out said, DON'T USE A 30 GRADE OIL IN THIS JEEP! IF THERE IS AN OIL PROBLEM WE WILL PULL A SAMPLE, AND THAT 30 GRADE WILL BITE YOU IN THE BUTT! IT CALLS FOR 5W20, USE 5W20!


Yeh......that worked at real well for some. Play it safe,really,are you sure?

For those of you who think you are safe doing 3000 mile oil changes with receipts,think again.....

<<<<<Manufacturer warranties might refuse to cover oil sludge damage by blaming you, the customer, for poor maintenance habits or neglect—even if you can prove you changed the oil every 3,000 miles. Without warranty protection, engine replacements are $5,000-$10,000. SAAB, Toyota, VW, and a few other manufacturers have some limited coverage for sludge damage.>>>>>

In sum..........playing it safe as some have said,may not be.....playing it smart!

The smart move is to use group IV synthetic,don't get sludge in the first place,and you won't have to worry about warranty issues......because you probably won't have any issues to deal with.

Point well taken Kirk, but if you use a mfg approved oil, and follow the intervals you'll be fine. That is unless there is a design flaw with the engine, in which case that would be a mfg issue they'd have to make good one. Just be able to show proof you've maintained the car as they outlined, using an approved oil and filter.

Even Amsoil had sludge issues in certain vehicles and suggests you follow mfg OCI's. These were design flaws and not the fault of the oil. I don't want to get the Amsoil boys all fired up again!

And once again, kirk posts a link that lists sludge prone engines....... engines are such due to design flaws.

You'll notice that not only does it say nothing about Grp IV oils, but asks and answers why all cars don't suffer from it. Notice the lack of the phrase Grp IV oil.....

But notice that A: They list certain years. B: The sentence "some manufacturers more than others due to various design differences.

C: Avoid buying car models that have very unusual oil sludge problems.
Change the oil every 3,000 miles.
On any vehicle, if you can't afford synthetic oil, check your owner's manual and insist on the correct weight of quality oil.
Buy high-quality oil filters on sale and bring them to your oil change.
You can change the PCV valve yourself, or have it changed with the 30,000-mile coolant service. But remember, coolant is best changed by a technician so they can dispose of the fluid properly.
Keep receipts for all your maintenance, even self-maintenance.

In other words, don't be a stupid owner. Notice the words "the correct weight of quality oil", another strike against "synlube".

Not to mention that he used this link before, and had it ripped apart before
