Q & A

"Are there any advantages to using plastic drums rather than steel drums for oil transport and storage?"

This is really a matter of personal/situational preference. Here are some features about each to consider:

Steel Drums

• Low up-front cost

• Returnable

• Widely used

• Estimated average cost: $0.38 - $0.45 (U.S.) per gallon

Drawbacks of Steel Drums

• Rust and body damage are common

• Heavy - 55 gallons, 450 lbs. (208 L, 204 kg)

• Difficult to clean

Plastic Drums

• Made of polyethylene

• 30% lighter than steel

• Cleaner (when new)

• Easier to roll

• Easier to clean (removable lid)

Drawbacks of Plastic Drums

• Plastic may swell

• Pumps and filter transfer carts can cause electrostatic charge and contaminant ingestion

• More expensive than steel drums

Today's Tip

• Consider using a portable filtration cart for filtering systems such as gearboxes. Carts can be configured with oil sampling diagnostic ports and water removing features. To avoid cross-contamination of fluids, use a different cart for each fluid type.

Book Bits

The best place to sample engine crankcase oil is just before the filter. Install the sampling valve between the pump and filter. This sample location is highly preferred over sampling from a drain port or using a vacuum pump and tube inserted down the dipstick port.
