View Full Version : Amsoil or not?

I asked what Amsoil had for the Cobra and the trans this was their response.
Any comments? I am thinking of going this route.





The manufacturer's specification for this vehicle is for 5W20 motor oil. We do offer this viscosity in our AMSOIL Synthetic XL7500 Series 5W20 (XLM). The drain interval on this product is 7500 miles or six months, whichever comes first. As an alternative, owners seeking longer drain intervals and/or higher levels of protection may use our AMSOIL Series 2000 0W30 Severe Service Motor oil (product code TSO). This premium motor oil protects better in high temperatures than do the higher viscosity conventional and synthetic oils. Series 2000 retains excellent fluidity in extremely low temperatures, so it flows quickly and reliably to allow easy starting and immediate lubrication protection.

The Ford manual trans in the car uses our AMSOIL Synthetic Universal Automatic Transmission Fluid (ATF).





Regarding the use of AMSOIL Synthetic Motor Oils in brand new or rebuilt engines, it is recommended, however not mandatory, that the motor be initially operated with petroleum oil up to its first normal drain interval. The advantages of doing this are as follows.

New engines or engine components generate high wear metals to begin with and generally contain debris from machining and assembly. It is more beneficial to allow these wear metals to collect in an inexpensive motor oil than to circulate throughout the crankcase for extended periods in a synthetic motor oil. By operating the vehicle to its first drain interval with a petroleum oil, these wear metals and manufacturing debris collect in the oil and are then flushed out of the crankcase when drained. This allows for a much cleaner operating environment for the synthetic lubricant.
Within the first miles of operation, if there are any defects in the assembly or workmanship of the engine components, they may be corrected before installing the more expensive synthetic motor oil. Occasionally, rebuilt engines may have re-machined components or materials which can sometimes be mismatched. These problems will develop in a fairly short period of time. If excessive oil consumption, leaks, or any other problem is noted, this should be corrected prior to changing to AMSOIL Synthetic Oil.

I have been using the 200 0w30 for over a year. It is expensive and hard to find but worth it.

I'm definately going to use Amsoil or Mobil 1 in my SVTF after the intial break-in period. I'm even thinking of taking it with me to the Ford dealer since they're supposed to do the freebie 3000 mile service. If they refuse to use it, I'll just take it back home and change it myself. I don't recall ever hearing anyone having complaints from using synthetic oil... maybe just that they won't try them because of the price. Hey, compared to $20-40k for a new car, 5 bucks a quart seems pretty cheap to me.

I've used Mobil 1 in all my air cooled engines (lawn tractor, etc) and have had zero problems. A couple years ago I bought a decent size air compressor. Got it home, dumped the oil that came with it in and started using it. As soon as it got below freezing in the garage, every time it tried to start it would moan, groan, not turn-over and end up tripping the circuit breaker. Went back and read the owner's manual (ya, could have done that in the first place) they approved the use of synthetic oil. I changed to Mobil 1 and now it fires up every single time no matter how cold. At one time my brother own 3 semi's and bought synthetic by the 55 gal. drum... swears by it.

Nuff of my rant. I don't have any technical back-up, just believe in the stuff. Think it's even more important in high-tech, high compression motors. Just my 2 cents.

Cheers ~ Jake

MidLifeC and/or vgr - I too am going to convert to Amsoil. Do you recommend an engine flush before upgrading to a synthetic?

I've been religious with the oil changes for the 14000 miles I've put on my SVTF.

I use the Amsoil 5W20. But wait until you have about 6000 miles on the engine before switching from conventional oil.
