^^^ That's exactly what one guy used to say.

You're "Oil Doc", are you not?

 

I think YOU are missing the point. At no more than $7/qt, plus no more than $5 per filter, that puts you somewhere around $45 an oil change. You are trying to save money by going longer on your oil changes, rather than to invest in a floor jack, some hand tools, and just do it yourself. Plus, regardless how much these oil manufactuers claim to be able to take your oil out, I doubt that is a good idea considering the filter is still going to pick up trash in that time, so why push it on an expensive car?

 

Do it youself-Walmart has the 5 gallon jug for $22.00, the oem filter cots$5.00. crush washer?
Drive up your ramps, dump, fill- you are finished in 30 minutes.

 

its all in your head bro


ive done the whole AMSoil thing,but now im back with mobile 1...same stuff

 

Unless there is something violently wrong with your oil, I can't fathom how you'd ever "feel" a difference.

 

Unless you didn't have but about a quart to start with.

 

Actually, every time I change my oil (in the evo and my old car), the car feels smoother and just better overall for the first few days. Nothing wrong with the old one - I change it every 2k miles or 3 months. It's weird but I can notice a difference too.

 

It's really a combination of things. Some oils do provide better wear protection than others. So, oil does matter. But it's more about the interval and ensuring you're changing your oil before it starts to break down.

Also, if you value your warranty, you have to follow the recommended oil change intervals listed in the owners manual. Regardless of what an oil analysis might tell you, if you don't follow the change intervals, Mitsu could deny warranty coverage of any engine part because you didn't follow the intervals.

To me, it's pretty simple.
- Change your oil within the recommended intervals.
- Choose whatever fully synthetic oil that makes you feel good and meets all of Mitsu's requirements.
- If you choose to do oil analysis, knock your socks off. It may show you that the oil you're using isn't protecting as well as another brand of oil. Or it may show that you need to change more often than the recommended intervals. But, don't go beyond the recommended intervals even if the oil analysis says you could. You'll lose your warranty if you do.

 

Can Mitsubishi definitely prove you went X amount of miles per oil change, if it ever came down to that reason alone being the defining point for voiding a warranty?

 

You may be required to provide proof of oil changes with receipts, so they can at least know how often you changed your own if you DIY. If you only have receipts for 3 oil changes but you have 30K miles, then they can assume on average you went 10K between oil changes. I don't think skimping on oil is worth it considering it's an evo. Based on the mitsu bulletin that was released a while back, I am now doing 3 month oil change intervals.

 

You wouldn't happen to have that bulletin? Or could post a link to it? I've heard of it and can't seem to find it. Thanks

 

By Law, a warranty cannot be voided due to maintenance practices (Intervals).

The OEM must prove that was the fault. By Law, they bear "The Burden of Proof"

Dealers always try to pull the wool over your eyes telling you this or that will void your warranty. A Dealer cannot void a warranty for anything. It must be done by an OEM Rep.

Actually, it is quite common to feel a difference between some oils.

A smoother running engine can be had just by switching to a Premium Synthetic.

Does everyone understand that if Mits tries to enforce the Mobil 1 part that they are "Required By Law" to pay for the M-1 during the Warranty Period ?

If you read that bulletin, 3000 miles "or sooner" , how do you know when to change ?

Check the oil every time you fill up with gas ?

I think a visit to the FTC Website is in order.
