My dam spent like 200-400 buck there the first time. He got my diff fluid tranny and all 3 other cars oil engine flush (they say to flush it before u put it in) and there filter.

 

Don't you have to work your way up to that. From what I've read and heard, you have to run your oil changes on a 3000 mile interval 2 times, THEN you can change it every 6000 miles. You'd still, however, have to change your oil filter every 3000 miles regardless.

 

Nope you do an engine flush buy there oil and filter. Put new oil in and its good for 25,000 IF you do a lot of highway driving. If you do short trips they say change it at 15,000.

 

The oil is debatable (whether it'll go that long), but I wouldn't trust a filter for anywhere near that long myself.

Your call though.

 

Go on there website and get the info that they have. It coated cyclinder wall 4X better than M1.

 

I'm not arguing with you, I do think Amsoil is good, but if you're going to believe claims about an oil, the last place you want to go is their own website. Look for independent studies.

 

+1.

Amsoil is good, I ain't arguing with you either, but a filter that goes 15,000-25,000 miles without a cleaning or replacement? Even if it does last somewhere near that number of miles, its filtration will be far worse than when it was new.

Like I said, its your call, but I wouldn't trust it. Amsoil is good, but remember, the companies are always selling you something. K&N is supposed to generate several more HP and give you X amount of MPGs, but it doesn't. Electric fans are supposed to give you back several more ponies, and X amount of MPGs, but they don't. Both of those do give you some of both usually, but not near what the manufacturers claim, or its so high in the RPMs our trucks will never see it. The new Hughes intake is supposed to give lots of extra HP and X amount of MPGs, and it does deliver some, but not what they claim (or to high in the RPMs). The list goes on...

If you look in the manual, IIRC, Chrysler recommends oil changes every 5000 miles with dino oil. It should be closer to 3000 (ish) miles, by most opinions. Thats a stretch of 40%. If Amsoil does that as well, it could be that you should change the filter every 9,000-15,000 miles. Now, I still think 9,000 miles is a long time, but thats better than 25,000 miles.

Just my two cents.

 

There are only 2 things I really care that my oil does:

1. Properly lubricate the working internals of the engine,
2. Suspend the particulate debris that results as a byproduct of combustion and engine wear.

I don't care about sheer coefficients, longevity, etc, etc. Honestly, I'm not comfortable leaving particulate matter in my engine for the time it would take to run up 25K miles or even 15K on the engine . I can't imagine that's beneficial to preventing bearing and journal wear, and coking between the piston rings.

Amsoil may be fine for 25K, but I doubt it significantly outperforms any other syn oil in the 5K intervals that I feel comfortable running. That's about as long as a trust a filter for anyways.

my $1.05 on the subject.

 

I have changed my oil and filter every 3k-4k miles since I have owned the truck, and I will continue to do so regardless of the recommendations of the oil makers. That's just how I roll. In my opinion, oils have probably gotten better, but the hype about oils lasting 10k, 15k, 25k between changes is mostly an advertising gimmick designed to appeal to the one main weakness ever person has - laziness. People will buy your oil if it means they don't have to do maintenance as often. I enjoy working on my truck though, so i'll keep doing my routine maintenance at 3k, and i'll never have to worry if my oil is getting to old or not.

 

regular purolator filter (L14670), or the PureOne (PL14670)?
