Way to reign it in LargeCarMan. The current .pdf states 2x drain interval up to 15,000 miles for gassers. Gasoline Engine Service Intervals will have to be capped there. Assuming your oil computer reminder comes on at 8,00 miles then don't violate this language or else the all-be-it denos in Superior will not honor anything exceeding my first bullet point while following the new ACD recommendations...this is a difference from prior to the launch of DEO/DME when they had long stated the 15,000 miles or one year, whichever comes first in mechanically sound gas engines (for at least 5 years prior).
• Oil drain intervals may be extended up to two times (2X)
the OEM* recommended drain interval (not to exceed
15,000 miles without oil analysis) or one year, whichever
comes first.
*OEM = Original Equipment Manufacturer
The 3x stuff is only mentioned in DEO and DME at this point, but yes I am assuming some of the Amsoil dealers have also provided an inconsistent message to their customers about this. Change has to be really hard for Amsoil to complete -considering their dealer base is so variable in terms of follow up training and not knowing if the dealers are reading the info on their excellent website (heck we have a 74 year old guy who's an outstanding spokesman still telling folks to run AMO in EVERYTHING here in northern Colorado). All and all though I can say that no oil provider provides as much change control info as Amsoil that is readily accessible to the general public. Now Schaeffer folks do provide rocking specs, but IMHO Amsoil has them beat in openly printing changes for dissemination.
