The following is just a sample of gas stations near I-80 between Davis and Reno to show the difference in price as you head east. From Nyack to Soda Springs there is only one station per exit, but from Davis to Auburn and in Reno there are many other choices not shown.
Prices Summer 2006 and 2008
1. Diff - Difference in price from the lowest price at the same dealer (Chevron, Shell, 76, ...)
In 2006 prices at Truckee were 5% (17¢) higher than those in Sacramento; In 2008 they were 13% (50¢) higher and prices in Auburn which were about the same were 5¢ higher for Shell and Chevron. The general rule to fill up at or before Auburn still holds.
Note: Tahoe gas stations raise their prices on the weekends. Prices are rounded down. $4.059 is shown as $4.05
The Arco AmPm on Douglas Blvd and Harding in Roseville and on Rocklin Rd.3 had the lowest price of the major stations sampled both years.
2. The Difference is shown following the / for 2008 prices. e.g. $4.49 / 50¢ means that price is 50¢ higher than the lowest price.
The 2008 survey was taken when prices were dropping, so some of the differences may have been a result of timing, one station dropped their price before another.
3. Arco AMPM only takes Debit Cards
4. Valerfo price is cash; credit is 10¢ more.
Note: If you use Chevron or Shell which are about 5¢ higher in Auburn it works out about the same driving to Tahoe if you fill up at Davis or Auburn. The 1.5 gal. (gas used in 45 miles from Davis to Auburn at 30 MPG) you use will mean you have to get an extra 1.5 gal. at Tahoe at 50¢ more/gal., but you will save 5¢/gal on the way up.
