1. Scenario: I am coasting downhill towards a stop sign. Can i shift directly to neutral without pressing in the clutch (as long as i take my foot off the accelerator).

2. I asked the dealership that changed my oil and they said they put in 5w-30 synthetic blend. I bought a quart 5w-20 SAE full synthetic oil. Can i mix the two. Don't know much about this except that conventional and synthetic dont mix. How do blends work?

Thanks in advance

 

1. Use the clutch for all gear changes, including to neutral.

2. You can mix the two. A blend is a mix of the two.

 

It is not necessary to use the clutch to change gears. It is advised to do so however, especially if you are asking the question.
