oil

[hamms-scooter]

I run mobil 1 fully synthetic in my chevy aveo and i was wondering how long you can go on Amsoil? I drive mostly Highway miles and currently change my oil every 9000 miles w/mobile 1. Just curious....

I go about 5,000 miles on a change on my Chev pick up. Probably 75% highway. Oil is cheap compared to a motor. I have never got cheap on my oil changes and my motors have served me very well.

using amsoil Harvey? seems like a waste if so. Good for your engine but for the extra price of it seems tuff to swallow

[harvey lee]

No I use Mobil 1. I don't look at it as a waste even though it cost a little more.

Good oil protection and a filter will give ones motor a long life.

I have used Amsoil and I would never say it was a waste.

When I change oil, I am not looking for the best deal but the best protection for the motor.

you are supposed to be able to go 25,000 miles with a filter change at 12,000. I run amsoil in my tahoe and change it once a year. we put on about 10,000-13,000 on the truck in a year. So for me, it's a once a year deal. As stated, more expensive, but I love the stuff!!! If you'd average it out, if I ran conventional oil, I'd have 3-4 oil changes a year, and have as much or probably more than an amsoil change into it.

I switched over to Amsoil a little over a year ago and use the 25k oil and filter. I went about 10K on the first change, and I'm at about 13K on the second one. I'm planning on changing the oil again around May, which would put me at about 10 months and 17K miles or so. One thing I do make sure is to check the oil level every few weeks or so and add if needed. My truck doesn't use much for oil, but ineveitably it does use a little keeping the same oil in for so long. Overall in the 23K miles or so that I've been running Amsoil, I've only had to add about 1/4 qt. Before I started using Amsoil, I was using Mobil 1 and changing every 6-8K.

I run AmsOil XL in my car and truck and change every 7K miles. Haven't tried their longer interval oils.

I run either 5w20 semi synthetic Motorcraft oil, or Valvaline 5w30, and I change my oil every 3-5k. I personally dont see any benefit of not having my vehicles in and inspected at any higher millage then that. Most of the time my vehicles have well over 100k on it, and I think things just need to be inspected on a regular basis.

AMSOIL gives you full lubricant warranty for up to 1 year/15,000 miles severe service (1/year/25,000 mile normal, but most come under the severe category) with: 0W-20 prod. code ASM, 5W-30 prod. code ASL or 10W-30 prod. code ATM

With the XL series up to 7,500 mile or one year.

The only way to know for sure is with Oil Analysis. My engine is still breaking in (Duramax Diesel) so I'm changing based on wear metals found in oil analysis. So, for me I had a few 5,000 mile/ 3 month intervals with non-synthetic. Since the last analysis showed the wear metals is down significantly (i.e.. the engine is now fairly well broken in) I plan on going one year or 15,000 miles with Amsoil. Of course at 6mths or 7500 miles I'll sample the oil, send to Blackstone labs, and then decide what to do. Every engine is different so it's best to know what's going on by using oil analysis. With my wife's car (2002 Cadillac) it's always burned a quart every 2-3 months (since new when my dad bought it) so by adding a quart the additive package is always pretty good. Performing oil analysis on her car showed that she really never needs to change the oil. Just change the filter once or twice a year and add oil when needed. I usually drain an extra quart out once a year and then top up. However, I do perform oil analysis on her vehical twice a year and the results are good so the no change oil change works for her vehical.

I don't know the cost of an oil analysis but I'm sure it's probably close to the price of an oil change. To me it just makes better sense to change the oil and the filter at regular intervals and not have to worry about it. Oil and filter changes are cheap insurance and it keeps those poor guys from having to stand on the corner at Spiffy Lube trying to flag down customers.

Oil analysis has it merits. It will tell you if there is a problem WAY before you will ever realize it otherwise. An extra oil change or two never hurts an engine, but it will drain out any evidence that could have foretold an upcoming problem.

That said, doing it regularly on everyday vehicles probably isn't cost effective with todays engines.
