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.
And once again, kirk posts a link that lists sludge prone engines....... engines are such due to design flaws.
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[/QUOTE]
Ripped Apart you say? Do you have a problem with the facts,tajan?
Rip all you want,trajan...doesn't change the facts...doesn't change history...doesn't change the truth!!
Trajan must be able to see the future when he buys a car to know it won't be sludge prone.
All engines today are sludge prone,some much worse than others. It takes years to discover which cars are the sludge monsters,Trajan.
In sum,I am 'ripping' your advice apart trajan,and well deserved at that!
Let's review Trajan's Idiotic Advice!
1. Buy a car not prone to sludge = Bad advice,impossible to know the future of any make,model,unless you buy used.
2. Change oil every 3,000 miles=Bad,antiquated,expensive,wasteful,advice.
3. Change PCV valve yourself = Not all models even have one now days. You also failed to mention to only use OEM valve if changed,and never use aftermarket valve. You could void the warranty with trajans advice.
4. Don't be a stupid owner = Bad advice.Need to define what stupid owner means. Most Americans only know where the key goes to start the car,and therefore are,"stupid",at least mechanically. That will never change,only worsen.
5. Change coolant every 30,000 miles = Trajan is living in the seventies,and is clueless.
6. Use the correct weight of oil = Vague advice, as weights are generally only recommendations,not mandates as per the manual.
In sum.........what the heck is Trajan talking about..........AGAIN....
Question..........who is actually listening to Trajan..........NOT ME!
