Which pump moves oil faster?

Both are rated up to 4 L/min, so real-world speed is close. The NORJIN only quotes a maximum of 4 L/min, while the LAYAN quotes a 1-4 L/min range, which is more honest about how flow drops as oil warms and thickens.

Neither brand publishes a lifespan figure. The LAYAN at least documents a 30-minute work cycle, so running it in bursts and letting it cool should extend its life. The NORJIN gives no duty-cycle guidance, which makes it easier to overheat.

Is the LAYAN worth the extra?

It is actually cheaper: $43.99 at Amazon as of November 3, 2026, against $45.99 for the NORJIN. You pay less and get more published specs, so there is little reason to pay more for the NORJIN.

Will either pump work on a boat or RV?

Yes. Both are 12V units aimed at cars, marine, RV, boat and motorcycle use, and both come with tubing for dipstick or drain-plug extraction. Check that your 12V source can supply about 5 A for the LAYAN.

Do I need to buy tubes separately?

The LAYAN includes a 6x800 mm copper inlet tube, an 8x1000 mm PU inlet tube and a 10x1000 mm PU outlet tube. The NORJIN listing only confirms the pump in the box, so confirm tube contents before ordering.

Which is better for diesel transfer?

Both are marketed for diesel and fluid transfer as well as engine oil. The LAYAN's metal gear-pump body and stated current draw make its limits clearer, which matters when moving larger volumes.
