I usually go with Mobile 1 for all my cars. Just got off the phone with a speed shop down the road who says they use Amsoil oils and filters. The weight is 0-30 and he says it costs about $10 per quart, so with the filter that puts me at about $200 for an oil change, depending on whether it's 8 or 10 qrts in my 94(i've gotton conflicting opinions on this). Any one have any input on this oil? Price is obviously high since I can get Mobile 1 at the Local store for a lot less. Thanks for any input.

Amsoil since the beginning for me. 67,000 miles on the Vipers. At least 3/4 million other miles since 1976 with many 20,000 mile oil change intervals backed up with oil analysis. This has hashed out more times than you can count. The base stock is the same as Mobil 1. In fact, I've heard rumor that they are Exxon-Mobils biggest base stock customer. It then comes down to the additive packages. They are a little different. I prefer the Amsoil. I have it in the tranny and rear end as well. They've been around since 1972.

The new filter, which it appears only a few Dealers are stocking , like Tator's and us, is the one developed with SRT Engineers from Comp Coupe racing experiences. It works with all Snakes , and is manufactured by Wix ( though it is different from the aftermarket one they make to fit a Viper ). We use Mobil 1 exclusively with the Vipers, and primarily use the new 0-40w recommended for many of the SRT products in the last few years.

Over the life of your engine, you could probably pay for a rebuild with what you save on Mobil 1 versus Amsoil.

Not to speak for Tom, but if you search his name you'll see that he uses non-synthetic diesel oil for the added additives diesel oils have. I follow his advice, but spend the extra (and probably unneeded) premium for fully synthetic diesel oil, Mobil's Delvac 1, 5w-40.

Tom Sessions swears by Motul, but there's a real $ premium for that.

I use to be an Amsoil distributor. The problem you run into with Amsoil it can make certain gaskets swell and then lead to leaks, especially on older cars that used regular oil rather than syntheics at an early time in their use. For the extra cost of Amsoil, its just not worth any additional benefits.

Ron,

I know you meant that tongue in cheek as it has absolutely no merit as to reality. I drive more miles than most who read this board. I've changed oil 10 times total over 68,000 miles. That's with oil analysis every time. Blackstone tells me to go longer each time I've sent them something. One sample to Blackstone had 10,000 miles with 2 track days and 3 autocrosses. They said go longer. That was my first time with the 0W-30. If I've put in 115 qts of oil over the life on the car I'm guessing that's maybe $300-400 more in oil costs than Mobil 1 ......but then you and most on here change their oil and filters at least twice as much as I do. Cost advantage to Amsoil. The Amsoil gear lubes I run are considerably cheaper plus I go 30,000 between changes, again with oil analysis. They also always come back 'suitable for further use.' I might add I'm running a 3:45 rear end which runs hotter because it's spinning more

Tom, and others have issues with Amsoil, but more centered around the marketing and official testing of it rather than the quality of the product itself. If I remember right, several years ago he once dissected the oil analysis results of my oil (6000 miles with track time) vs 1500 easy Mobil 1 miles. As I remember it, the nod went to the Amsoil.

Hi Steve,

Yes, you read me right, tongue in cheek. Certainly though there is an element of truth regarding the savings of not using something more expensive than Mobil One, using that as the base given that it's the factory fill. I'm not anti-Amsoil as I'm not knowledgable enough on the product to have an opinion. Purely a mathematical comment.

Based on Blackstone's averages for Viper UOA, you are extreme as far as miles driven per change. Blackstone used to include all Dodge V-10's in their averages including Ram Truck iron block units until I explained that the engines were completely differant. That brought the avg mileage per change way down.

Many Viper owners change their oil annually at less than 1,000 miles. I'm about 2,000 miles per change. On my other vehicles, I'm more like you at about 5,500 and yes, Blackstone tells me the same thing.... run the oil longer. Not being a fleet owner, I don't really care to run it longer. I purchase UOA for the piece of mind instead.

Really? 12 qts?

I've changed my oil close to 20 times now in my 01...and every time 9.5qts puts it right on the spot
