Peterson Fluid Systems Dry Sump Oil Tank, 8 qt
Best for higher-capacity dry sump setups, the 8 qt tank is fully baffled inside for oil and air control, with aluminum construction and a natural finish. This tank is well-suited for performance builds where oil separation and air management are critical. Best for enthusiasts needing reliable volume and strong oil management. A limitation could be larger footprint in compact engine bays.
Peterson Fluid Systems 08-0009 3 Gallon Dry Sump Tank
Best for compact builds or racers needing a smaller dry sump reservoir. This 3 gallon tank features female AN 12 bungs and a single return inlet, making it straightforward to integrate with standard AN fittings. Choose this if space is limited or you’re upgrading a smaller engine. Limitation: smaller capacity may require more frequent oil top-ups in heavy use.
Peterson Fluid Systems 08-0011 4 Gallon Dry Sump Tank
Best for mid-sized dry sump applications, the 4 gallon tank provides a balance between capacity and space. It has a single scavenge inlet and measurements of about 19 inches in height and 9 inches in diameter. Choose this if you need moderate capacity with a compact vertical footprint. A potential limitation is the single inlet configuration which may require careful plumbing planning.
Zerostart 3400034 Silicone Pad Heater
Best for warming engine oil and related fluids when mounted on smooth metal surfaces. The 5″ x 7″ pad provides 500 watts at 120 volts and is CSA approved. Best for universal use on engine oil reservoirs or compatible pans when a dedicated tank heater is not available. Limitation: pad heating may require precise surface preparation and wiring for optimal heat transfer.
Buying Guide
What size dry sump tank do you have? Choose a heater that fits the tank’s dimensions and capacity. For larger tanks, consider units like the 8 qt Peterson tank or multiple heating options to ensure even warmth. Do you need built-in baffling or air-oil separation features? Tanks with internal baffling improve oil control and reduce aeration during warmup. Is installation space limited? Compact tanks (3–4 gallon) with straightforward fittings can simplify mounting. Do you require quick starts in very cold climates? A dedicated oil tank heater like Stef’s 6770 or a silicone pad heater can provide faster heat-up times. Consider the type of connection (AN fittings, hoses) and your existing plumbing when choosing a model.
