A Brief Comparison Table

My Experience With Schaeffer Oil Vs Mobil 1

I kicked off my oil adventure in February 2025, fed up with my pickup’s sluggish starts after a frigid January.

On February 10, I grabbed Schaeffer’s Supreme 9000 5W-40, a full synthetic with a moly twist, and swapped it in after a messy drain.

 By February 15, my engine purred smoother on a cold morning drive—impressive for a first try!

Mobil 1 entered on February 20 with its Extended Performance 5W-30, promising 15,000 miles, and I poured it into my sedan after a quick flush.

By February 25, it handled a hot commute without a hiccup, though the price tag stung a bit.

March 5 brought a towing job, and Schaeffer’s shear stability kept my pickup’s oil thick under load, while Mobil 1’s Anti-Wear Tech protected my sedan’s engine during a steep climb.

On April 10, a rainy day test showed Schaeffer’s moly additives fighting rust on my pickup’s valves, but Mobil 1’s cleaner finish left less residue in my sedan.

June 1, during a cross-town haul, Schaeffer’s custom blend quieted my pickup’s upper engine noise, while Mobil 1’s widespread availability saved me a last-minute store hop. Now, at 02:23 PM +06 on July 07, 2025, after 147 days of city drives and rural treks, I’ve tracked their quirks—Schaeffer’s niche strength shines, while Mobil 1’s reach wins for convenience. You’ll see how they fit your ride, so let’s roll through my garage saga.
