Anybody here use Amsoil? I'm considering switching from my current dino oil (Castrol GTX 5w-30) to either Amsoil Series 2000 0w-30 or Regular Amsoil 5w-30.

Does anybody change at the 25,000 mile interval recommended by Amsoil?
If you do, how many miles are currently on your car/truck?
Do you use the Amsoil Superduty filter?

 

I have heard nothing but the absolute best about Amsoil products. When I change my trans and diff fluids, that's what's going in. I would even use their oil if it was easier to get, but I'm a huge Mobil 1 fan. I piped in here to tell just one thing. There's no friggin way on god's green earth am I gonna go 25,000 miles on an oil change. Don't care what that stuff is made out of, or what you can say or proove. No way. There's alot of guys that do it and love it, but there's alot of guys that stand behind me too. (Hopefuly they will help me out now)

 

I agree with Galaxy, no way I am going over 3,000 - 5,000 miles without changing the oil. I agree Amsoil is a great quality motor oil but it is no better then other great quality motor oils, Mobil 1, Redline, Royal Purple, Valovine to name a few.

The only real difference between Amsoil and the others I mentioned is Amsoil is more money, and much harder to get. The choice is yours, but do NOT be mislead into believeing that Amsoil it THE best oil it is not, it is a top quality motor oil EQUAL to other top motor oils.

I don't care what any test results may show because going 20,000 to 25,000 miles or more between oil changes is just out of the question.

Some will tell you that you can have it analyzed, and to change the filter I think every 5,000 miles or what have you, but neither make much sence to me.

Why wait on the oil to be analyzed to tell you it needs to be changed? How long do you have to wait on test results? Why change the filter and not the oil? Filters do collect MOST of the junk in the oil, but that is it MOST, so why not change the oil so EVERYTHING is clean and new?

The point being is Amsoil is more expensive and alot of people tell you they use it because they don't want to have to change it as often and that offsets the cost of it. If someone dosn't want to change as often is like telling me they don't want to because they don't have the time to do so. If that is the case I find it hard to believe they would actually take the time to analyize the oil to begin with or even change the filter before the next oil change.

The choice is yours, but if your still under warranty I would highly recommend you stay with the oil change interval recommend (which I believe is every 5,000 miles) so if you do as your warranty recommends, and you use Amsoil your just throwing good money away since the other oils I mentioned protect just as well, no quetion.

 

As far as the 25,000 miles.

You must also remember that it's either 25000 or 1 year whichever comes first.

It's been my experiece that most folks are going about 12-15K miles in a year.

Also you must change filters at 6 months or 12500 with Amsoil SDF filter. This is an important item because this will top off your oil with fresh additives and proper viscosity.

I have seen the viscosity deviate about 1 grade over the coarse of a year. Although wear metals were usually on the low side. So the viscosity is not as importart, if it is still protecting.

BTW, I have seen analysis on conventional oils that have changed viscosity in less than 3,000 miles--Usually they will thin out at first(the VII's are breaking down) then after that, the oil cannot proctect, the engine runs hoter, then the oils will thicken up. (Causing Sludge and Varnish in the process)

Amsoil's oils will not do this. I have seen engines with over 100,000 with the oil being changed at 25,000 miles and the engines are very clean.

I will say this, in your area of the country, the 0w30 will give you the best protection that you can get. Bot Extreme cold protection and the best hot weather protection.

 

I currently put between 20k - 25k miles on per year. I'd put even more on if I didn't ride my motorcycle in the summer. The savings alone (I currently change at 3000 mile intervals...long before I see 3 months) would be worth the switch. My truck has over 115k on it now and I would like to think it's gonna hit at least 200k before it needs any major engine work. I like the idea of synthetics, but could never see the reason to spend that much $$ because I thought they also needed changed at 3000-5000 miles.

I've had friends tell me I'm nuts for thinking about going over 5000 mile without an oil change. I also thought it was kinda wierd when GM came out with the trailblazer with a recommend change interval of 15,000 miles.

Hmmm, I'm still confused.

 

What I would recommend you to do if you don't trust the interval.
1. take an oil sample with your current oil at your currenty interval.

Then switch over and take a sample at the same interval. If it looks good, double that. If that looks good double that. So you say. 3,000 then 6,000 then 12,000. No problem.

If you want I can show you my last oil sample with over 10,000 miles but over the coarse of 18 months this was before I put my by-pass on. Now its been almost 2 years and 20,000 miles since my last change. I will be sampling in the summer before I change out filters.

Hope this helps.

 

OK, I know I'm in the minority here but I go 25,000 miles between oil changes with Amsoil and I have had NO problems. It takes a long time to get over the tried and true 3,000 mile change but once you are over the thought all you have to do is enjoy the benifits. I not only run the Amsiol in my own car and truck, I have about 30 customers on it. They range from some one that only drives about 7,000 miles a year to county police cars that put on about 35,000 - 50,000 miles a year. I have never had one oil related engine problem in the 5 years that I have been useing/installing it. I think that if it can handle the squad cars(and I know how they get driven because I drive one too....It ain't pretty) then it shopuld be good enough for your daily driver. It would go good in your motorcycle too.

If you have any questions please ask.

Good luck,
Mike

 

I use redline, and that stuff is over $8 per quart! Even though the extended drain interv. is said to be 18,000 mi., while still on warrenty, I change mine every 5,000. Tranny is every 15,000.

 

Generally the 25,000/1 year interval is for normal service vehicles. If you use your truck in the servere service catagory you will have to use short drains.

You can go here to review the drain interval chart: http://www.amsoil.com/lit/g1490.pdf

Medic,

I responded to your email did you get it?

Just wondering.

 

I've been going 1 year (less than 25,000 miles) on my truck for more than 18 months and now all three of my vehicles are on Amsoil.

A 98 Taurus that was converted at 60K, a 90 Honda Civic that was converted at 125K, and the truck which was converted at 37K.

No problems. When I put in the Amsoil, the engine was quieter. When I put it in the transmission, the shifting was much smoother.

It's good stuff. And for what it's worth, msparks knows what he is talking about!
