any of you using amsoil?

using their oil filter too?

opinion about it?

when are you changing your oil?, amsoil says 9k (3x regular) for compressed engines

 

I've been using amsoil for about 10,000 miles and i love it. I use their oil, their oil filter as well as their synthetic transmition fluid. You wont be disappointed.

I change my oil every 3,000 miles, i just dont feel comfortable running on the same oil for 9,000 miles.

 

Not too many people use the same oil for 9,000 miles.

 

Amsoil in the tranny and Amsoil motor oil my first synthetic oil change. Have since gone the Mobil 1 route because its so easy to find. I change my motor oil at the 3/3.5K mile mark also. I just can't see running oil that long (9K miles)

 

Why would you spend that amount of money on Amsoil just to throw it down the drain well before the life of the oil is even close to being used up? If anything, pull the filter and replace it and then top off your oil. You could easily bypass one or two oil changes. If you want to change every 3,000 miles, then use a quality dino oil like Chevron or Castrol. Even those oils will perform up to 5,000 miles in normal conditions. To many people buy into the Amsoil or synthetic oil stories and then don't even take advantage of it. Synthetics will perform better in extreme rpm or high heat situations (or extreme cold) which the Lightning does not fall into that category. Oil related failures are extremely rare in todays engines.

 

It's all about that extra .1 in the quarter. Atleast for me it is.
Oil is the cheapest thing you can buy for your truck that does the most protection.

So it cost me an extra $26.00 every 3500 miles changing the oil myself. IMHO, well worth the cost

 

9,000 mile would be a little over a year in my truck without changing the oil. I change my truck every 3,000 with mobil 1

 

Ill go about every 3000 miles. But 9000 miles..

 

I don't care what kind of oil it is, 6 quarts of oil can only hold so much dirt/crud, blowby, combustion contaminants, etc. 6 quarts is 6 quarts, no oil should be left in an engine for 9000 miles. I change my oil every 2500 because its a nice round number (2500, 5000, 7500, 10,000... you get the idea) and because it's free and easy for me. as for Lightnings not falling into extreme heat or cold situations, I for one think it gets pretty damn hot inside a supercharged engine with 4 or 500 horsepower that's pushing a 5000lb truck around. and we have numerous members here from cold places like Canada, Alaska, and other northern U.S. areas. Oil related failures are not as uncommon as you might think, especially with the VERY tight tolerances on the modular engines. not to mention ford's oil controlled variable cam timing...

just my .02

Although the heat produced by a Lightning engine can be on the higher end of a production vehicle it isn't hot enough that a good conventional dino oil can't handle. I appreciate your input regarding contaminants in an engine, but unless you're doing oil analysis, you don't have any accurate data for comparison. Oils have many additives that combat the contaminants and keep them from harming the engine. Even though you say your oil is free, you're still wasting a lot of good oil with a 2500 mile oil change. I'm not judging anyones maintenance schedules, but the oils are made to go a lot longer than people give them credit for. I've been in the business for 25+ years and seen many documented facts regarding the composition and analysis of oils and dino oil will do an excellent job at 3,000 miles and synthetics, with proper set up can double that and in some instances can triple it.

As for oil related failures, I would venture a guess that it was a vehicle that wasn't properly cared for or oil starvation due to mechanical failure or a design flaw. I would agree you that extreme cold paces that can be found in Canada and Alaska are prime candidates for a synthetic as they can reach temperatures that a dino oil won't perform adequately.
