Amsoil HP in Evinrude "E-TEC" Marine OutboardQ: A boat owner asks, Can I use Amsoil HP in an Evinrude e-tech outboard? A: Yes you can I replied. Read our Marine E-TEC Field Study below. Our Synthetic 2-Stroke marine Oil provides excellent protection in Evinrude engines programmed to the lean-mix setting. Amsoil warrants its use according to the AMSOIL Limited Liability Warranty.
Evinrude® E-TEC™ marine engines are unique in that they offer an alternative, lean-mix setting that allows the engine to use less oil. Whether programmed to operate at the standard mix ratio or reprogrammed to the lean-mix setting, these engines use sophisticated electronic equipment to monitor conditions, including rpm and throttle position, to determine the appropriate gas-to-oil mixture. To use the lean-mix setting, however, customers must have their engines reprogrammed by an Evinrude dealer and agree to use Evinrude XD100™ oil exclusively, often at a higher cost compared to other oils. Bombardier Recreational Products (BRP®), the manufacturer of Evinrude engines, has not established a performance specification against which to qualify other oils.

Based in Naples, Fla., SEA-TOW typically tows large marine vessels, including yachts and sport cruisers. The engines that power their towing vessels routinely encounter heavyduty, high-stress operation and provide the ideal environment for testing motor oils. Both Evinrude 250 hp E-TEC engines used in the study were initially operated on the standard oil injection setting for 28 hours. An Evinrude dealer then reprogrammed both engines to operate on the lean-mix setting for the duration of the study. The starboard engine’s oil reservoir was filled with AMSOIL HP Marine Synthetic 2-Stroke Oil, the portside engine’s oil reservoir with Evinrude XD100 2-Cycle Oil. The validation period lasted a total of 534 hours; approximately 240 hours were spent under severe-service conditions when the SEA-TOW boat towed marine vessels. The engines were closely monitored for the duration, and upon completion, both were disassembled and rated by a calibrated ASTM rater who evaluated each engine based on NMMA TC-W3 criteria for two-cycle marine engines. Merit ratings for each set of components (e.g. piston skirts, piston rings, etc.) were determined using the appropriate techniques and rating scales as defined in the Coordinating Research Council, Inc. Deposit Rating Manual No. 20. The evaluation included an examination of the condition of all engine parts. Some components received a merit rating based on a 1-10 scale, with 10 representing a component free of defects and 0 representing catastrophic distress. AMSOIL HP Marine Synthetic 2-Stroke Oil Piston Varnish 8.52 Piston Skirt Condition (scratching) Piston Scuffing 0.00% Evinrude XD100 2-Cycle Oil Piston Varnish 8.57 Piston Skirt Condition (scratching) Piston Scuffing 0.00% The pistons in both engines received nearly identical high merit ratings for varnish, indicating both oils excelled at inhibiting varnish formation. Scratching refers to the alteration of the skirt surface in the form of sharp linear depressions from lapping of mating surfaces by fine particles suspended in the lubricant, fuel, air or imbedded in a surface, while scuffing appears as a matte finish. Piston Rings & Lands AMSOIL HP Marine Synthetic 2-Stroke Oil Top Ring Sticking & Deposits 10.00 Second Ring Sticking & Deposits 10.00 Crown Land Deposits 3.98 Second Land Deposits 5.91 Evinrude XD100 2-Cycle Oil Top Ring Sticking & Deposits 10.00 Second Ring Sticking & Deposits 10.00 Crown Land Deposits 2.99 Second Land Deposits 6.82 Deposits on the piston rings can cause ring sticking and consequent power loss. The top rings and second rings in both engines earned perfect merit ratings of 10.00, demonstrating no piston ring deposits. Merit ratings were similar for both engines. Cylinder Heads AMSOIL HP Marine Synthetic 2-Stroke Cylinder Head Deposits 8.76 Evinrude XD100 2-Cycle Cylinder Head Deposits 8.14 Excessive cylinder head deposits are undesirable and can negatively affect engine performance. Both oils earned high ratings for deposit control, indicating good cleanliness properties. Piston Crowns & undercrowns AMSOIL HP Marine Synthetic 2-Stroke Piston Crown Deposits 7.02 Piston Undercrown Deposits 2.18 Evinrude XD100 2-Cycle Piston Crown Deposits 6.31 Piston Undercrown Deposits 2.66 While undercrown deposits do not impede performance, heavy piston crown deposits can cause preignition and consequent poor performance. Two-cycle oils must resist heavy deposit formation on the piston crown caused by the high temperatures inside the combustion chamber. HP Marine demonstrated strong performance in the area of piston crown deposits. Connecting Rod Assemblies AMSOIL HP Marine Synthetic 2-Stroke Oil Wristpin: Condition/Deposits 6.82 Rod Bearing, Crankpins: Condition/Deposits 9.90 Rod Bearing, Wristpins: Condition/Deposits 8.38 Evinrude XD100 2-Cycle Oil Wristpin: Condition/Deposits 8.38 Rod Bearing, Crankpins: Condition/Deposits 9.88 Rod Bearing, Wristpins: Condition/Deposits 7.62 Connecting rod assembly components are exposed to elevated temperatures and pressures that can rupture the oil film, leading to metal-to-metal contact and wear. The wristpins, crankpin rod bearings and wristpin rod bearings in both engines demonstrated trace to light levels of wear and were found to be in “good” condition according to the calibrated ASTM rater. Deposits on all components were limited to levels not adversely affecting performance. Connecting Rods AMSOIL HP Marine Synthetic 2-Stroke Oil Wristpin Bearing Race: Condition/Deposits 7.90 Crankpin Bearing Race: Condition/Deposits 9.67 Evinrude XD100 2-Cycle Oil Wristpin Bearing Race: Condition/Deposits 7.98 Crankpin Bearing Race: Condition/Deposits 9.73 The wristpin and crankpin bearing races undergo constant rotational stress, inviting wear. Bearing races in both engines demonstrated trace to light levels of wear and were found to be in “good” condition according to the calibrated ASTM rater. Deposits were limited to low levels in both engines. Cylinders AMSOIL HP Marine Synthetic 2-Stroke Oil Exhaust Port Blocking 1.08% Exhaust Port Deposits 9.89 Cylinder Bore Scuffing 0.00% Evinrude XD100 2-Cycle Oil Exhaust Port Blocking 1.17% Exhaust Port Deposits 9.88 Cylinder Bore Scuffing 0.00% Carbon deposit buildup in the exhaust ports restricts air flow and can cause reduced power and poor overall performance. Both engines displayed virtually no exhaust port blocking, represented by the low percentages. Deposits were likewise minimal, with ratings near perfect 10s. In the area of cylinder bore scuffing, both oils limited metal-to-metal contact and achieved perfect scores of 0.00 percent. The cross-hatch pattern remains visible on the cylinder walls of both engines. Crankshafts AMSOIL HP Marine Synthetic 2-Stroke Oil Crankshaft Crankpin: Condition/Deposits 9.85 Crankshaft Main Journal: Condition/Deposits 9.78 Evinrude XD100 2-Cycle Oil Crankshaft Crankpin: Condition/Deposits 9.85 Crankshaft Main Journal: Condition/Deposits 9.78 The crankpins and main bearing journals experience elevated pressures during operation and represent common suffering points. In both engines, the crankpins and main bearing journals demonstrated trace to light wear and were found to be in “good” condition according to the calibrated ASTM rater. Ratings for deposits were nearly perfect for both engines. Main Bearings AMSOIL HP Marine Synthetic 2-Stroke Oil Crankshaft Main Bearings: Condition/Deposits 9.95 Evinrude XD100 2-Cycle Oil Crankshaft Main Bearings: Condition/Deposits 9.89 The main bearings experience intense pressure and represent a common area where metal-to-metal contact can occur. Both oils limited wear to trace to light levels and the bearings were found to be in “good” condition according to the calibrated ASTM rater. Both oils nearly eliminated deposits as well. Conclusion As demonstrated in real-world, severe-service testing, AMSOIL HP MarineTM Synthetic 2-Stroke Oil meets the stringent performance needs of Evinrude® E-TECTM marine engines programmed for reduced oil consumption. Operated simultaneously with an engine lubricated with Evinrude XD100, an identical engine lubricated with HP Marine demonstrated strong performance and excelled in critical-component lubrication. The cylinder bores, for example, demonstrated 0.00 percent scuffing, while the main bearings demonstrated only trace to light wear. The engine also displayed no ring deposits, earning perfect merit ratings. Finally, HP Marine effectively limited deposits throughout the engine and met the increased performance demands required by the lean-mix setting. Results prove the effectiveness of AMSOIL HP Marine Synthetic 2-Stroke Oil in Evinrude E-TEC applications. AMSOIL fully supports the use of HP Marine as a replacement for Evinrude XD100 in Evinrude E-TEC engines, and warrants its use according to the AMSOIL Limited Liability Warranty (G1363).
