Mobil 1 - What's recommended

ServoScanMan · 05-11-2006, 11:05 PM

I have not changed the oil yet on my new Prius. What is the recommended weight? 10W-30? Does anyone know how much oil (with a filter change) the ICE will hold? Thanks!

benighted · 05-11-2006, 11:12 PM

it takes 5W-30 and 3 quarts of it

I think the manual says 5W-30 and 3.9 qts. (nice round number). Have to be careful not to overfil with the complete last quart.

Is it only 3 and not 3.9??

There have been many posts with complaints about the dealerships overfilling the oil, the 3.9 number in the manual might have something to do with it.

When I change my oil I pour in 3 quarts and add more if it needs it, but it never takes more than 3.5 quarts.

If you take it to a dealer for changing, some will allow you to bring in your own oil. Give them 3 quarts and tell them you'll put in the rest. If you give them 4 quarts, they'll be inclined to put all in.

3.9 is a misprint. when filling a dry engine it takes 3.9. under normal oil changes, you will never get a dry engine, there is usually about 1/2-3/4 of a quart still in the engine. i would suggest 3 quarts and check the level. 3.25 seems to work well for me though.

You sure about that? My change took just short of 4 quarts.

I just don't see how putting a quart less could raise fuel economy, in any case, as some has suggested in other threads.

Your Owner'a Manual has extensive information regarding ICE lubrication. Try Section 8-2, page 283 and 312 in the back section.

My dealer refused to do it with three bottoles of Mobil-1. I had to run to a auto shop to get an extra one.

Did you actually 'run' to the auto shop?

Thank you all for your replies. I think (when it's time) I will drain oil, change the filter, fill with 3 quarts of Mobil 1 and check the level.
