Which is better for a 24V truck or RV?

The SYHXYSOO. It runs on 12V and 24V, while the NORJIN is 12V only.

Is the SYHXYSOO worth $34 more?

Only if you need 24V support or the adjustable flow and full tube kit. For 12V cars only, the NORJIN does the same 100W, 4 L/min job for less.

Do both extract oil at the same speed?

Their top rate is the same at 4 L/min. The SYHXYSOO lets you slow the flow to 1 L/min for thick fluids; the NORJIN runs at its fixed rate.

Which comes with more in the box?

The SYHXYSOO. It includes two 1.5m tubes, a fixed clamp, four anti-leak plugs, a waterproof switch and instructions. The NORJIN ships as the pump with tubes.

Can either pump transmission fluid or diesel?

Yes. Both are fluid transfer pumps rated for engine oil and similar fluids; the SYHXYSOO's adjustable flow helps with thicker gear oil and transmission fluid.

Both use a 100W motor and neither lists a warranty or service life, so there is no clear durability winner. The SYHXYSOO has 11 ratings averaging 5 out of 5; the NORJIN shows none.
