mobil 1 10w40 oil
I know our car needs 0-40 oil but the walmart and costco in my area doesnt have any. So i bought 10-40 mobil 1. Is it ok to use this oil for a few thousand miles? What will happen if you start using a 10-40 oil? 10-40 is much easier to find than a 0-40
Thanks

It does not matter where you live or the climate. It does not matter if the oil weight is "close" meaning the numbers are similar. There are totally different additive packages in different weight oils, meaning an oil with a similar number can provide a totally inferior level of protection.
There is apparently a 5w40 non-ESP. It is not listed on the Mobil website. I have never actually seen it in a store. Most 5w40 is the ESP, which stands for Emission System Protection. It is designed to work with the new Blue Diesel motors with special emissions equipment. It is for diesel motors only, not gasoline.
If you live in the US, there is absolutely no reason to use anything other than 0w40. The 5w40 ESP is not meant for the AMG or gasoline motor, and the 5w40 non-ESP, if you can actually find it, is not going to be any better or cheaper than the 0w40.

Pumping however many times is worth not having to ramp the car and get under it. If he's that lazy, he should have gotten the pneumatic version that hooks up to a compressor and pumps for you.
Also, you pump, then go get a beer, then come back, and pump more. There's a limit to how much suction the thing can generate and how fast the oil can come out. You don't need to continuously pump until it's empty. Pump, wait, pump, wait.
