After All These Years, Mobil is Still Trying to Catch Up! MOBILE 1 EXTENDED PERFORMANCE OIL Now Offering 15,000 Mile or 1 Year Oil Drain Intervals! AMSOIL MOTOR OIL Still Offering 25,000 Mile or 1 Year Oil Drain Intervals!

In February 2005 Mobil 1 released a few new lines of oils offering longer drain intervals. One of these included a full synthetic advertised as having 15,000 mile or one year drain intervals. Mobil is trying to make the consumer think they are the first to do this. Facts are that Amsoil has offered 25,000 mile or one year drains for over 30 years, longer than Mobil 1 has even been on the market. The industry recognizes this as well:

"– the company [Mobil] claims to be “the first oil company to introduce a line of high-endurance motor oils designed for longer oil change intervals,” as recommended by many automakers today. That may be overstating it a wee bit (for example, Amsoil Inc. of Superior, Wis., for decades has sold a line of synthetic oils offering guaranteed performance and long drain intervals)...."

In 1972 Amsoil released THE FIRST API rated Synthetic Motor Oil, promoting 25,000 mile or one year drain intervals. Mobil 1 was introduced in 1974, basically acknowledging that Amsoil was correct: that there was a market for synthetic motor oils! Since then nearly every oil company has introduced a synthetic of some type and is OEM fluid in many new vehicles. Now Mobil is offering this new oil to keep up with the gradual shift towards extended drain intervals that are currently being recommended by various auto manufacturers. So once again Mobil is acknowledging what Amsoil has recommended with their oil since 1972: extended drain intervals!

What makes the new Mobil 1 better than the old Mobil 1? According to their own Web Site:

Mobil again is acknowledging Amsoil, by saying that using a better additive package can make a better and longer lasting oil.

For years people accused Amsoil of being overpriced, but the new Mobil I have seen costing as much and in some cases more.
