Mt. Si Chevron is a busy and highly adequate gas station. It is easy to get into and offers fuel, a car wash, and bathrooms. The store provides an exceptional variety of choices, including drinks, snacks, and an amazing selection of Slim Jim's and cheese snacks. It is typically clean, well manned, and fully stocked. The location serves as a great stopping point, though fuel lines are often long and turning left onto the highway can be tough. Gas is more pricy at this location on the hill.
They recently converted into a Sinclair, dinosaur and all outside, so far gas is just as expensive as Chevron was. Looks cleaner now

Nice people. Gas is a little high even for today's standards but they have a good stocked little market and the people behind the counter are friendly.

Clean, good snack variety. Has a reader board with pass conditions. Pleasant, professional staff. Easy access from freeway.
