When should I start using synthetic oil??

[Lazerdot]

I changed to Amsoil at around 2500 miles. I use the racing oil as opposed to the extended drain interval oil because of the AX and TTs I'm doing. I went to 9000 miles on that change.

Amsoil compares very favorably with other synthetic oils and is priced competitively especially when the extended drain intervals are considered.

Amsoil is a pure synthetic oil and is used in many racing venues and is the title sponsor for the TRAXXS Offroad Truck Series this year.

I am using the Signature series oils and extended range filter in a 06 Honda Civic (wife's), my 04 FORD F-250 and use the 2 cycle racing oils in my 7 go karts (Yamaha KT 100s and Rotax 125) used for my karting school and personal racing.

Motul is huge in karting by the way. It retails around here at about 1/3 more and must be mixed at a higher ratio. My KT 100s were using 1/20 Motul mix and now use a 1/30 Amsoil mix and could go as low as 1/50. I use the same 1/40 mix with Amsoil as Motul in the Rotax.

There are many partial and full synthetics available, obviously I'd like people to compare and consider using Amsoil.

I'm convinced Amsoil is a high quality and economical product for all my uses.

Of course I'd love to see my Amsoil business (TruLube.com) do well with the Yaris folks and others, but people have there own opinions and trying to convince otherwise is, as they say, futile.

Please check out my Store Front and delve into the information provided by Amsoil and decide for yourselves.

But I'm right about the XL series being group III, right? Says so on their website. And there are theories about their group III XL series (their only API approved series) about it not even being 100% full synthetic, since the "100% synthetic" claim is somehow missing on the front label of the XL bottles, while proudly stated elsewhere on so many of their other products.

If you're going to use extended drain intervals with synthetic oils, you'd better be certain your driving is of the extended interval sort. I damaged a couple of engines back in the '70s-'80s by adopting the 25K mile change intervals Mobil 1 used to recommend. I'm of the opinion that unless you're doing exclusively extended engine-on runs, either long highway trips or the sort of constant running that taxicabs do, that frequent changes are important regardless of what oil you're using, and that if you're changing the oil frequently you have little to gain from synthetic oils. I'm not using them now and don't plan to.

You're right about that.

Amsoil describes the type of use that applies to the extended drain intervals.

Some folks definitely need to reduce the change interval, but many others can benefit from the higher interval.

We use the 100% signature series and even if we decide to do a shorter drain interval based on driving habits we can still save some dollars and I don't worry about getting a change nearly as often.

There are plenty of opinions and personal preferences for sure. I am confident the facts speak for themselves and leave it to everyone to do what they think is best for their situation.

I'll try to provide some links later, but now must get the car ready for the Porsche Club Time Trial coming up. 3.2 miles of track with just three cars with you each run. Hopefully my little cameras will work this time...

Any one got any links to Mobil1's non viability as a true synthetic?

The facts to backup my previous statements about XL series being group III, and having labels that omit the "100%" synthetic claim...
