Hot Shot's Secret Green Diamond 10W-30 is a full synthetic CK-4 engine oil in a 1-gallon jug, built with Hot Shot's patented FR3 friction reducer. It isn't engine-specific, so use it wherever your owner's manual calls for 10W-30. It also meets Ford Specification WSS-M2C171-F1 for added wear protection, which not every CK-4 oil does.
Fitment
Oil fits by grade and spec, not by year or model. Check the viscosity and oil specification in your owner's manual, then compare it to this jug: 10W-30, full synthetic, and rated by Hot Shot's as exceeding the API CK-4 specification. Hot Shot's also states that its HSS 5W-40 and 10W-30 Green Diamond Fleet oils meet the requirements from Ford for added wear protection in Ford Specification WSS-M2C171-F1. Not all CK-4 specification oils meet both the CK-4 and the Ford specification, so if your manual lists WSS-M2C171-F1, this is one that does. Make sure the 10W-30 grade matches too. Not sure? Verify by VIN or call us.
Why this part
Green Diamond Fleet Oil was formulated for severe operating conditions: hauling heavy loads, stop and go driving, and running in areas with high airborne particulates. It is a fully formulated CK-4 motor oil with high detergency plus strong oxidation and thermal stability. That combination prevents deposits and oil breakdown, and Hot Shot's says it makes longer drain intervals possible. The FR3 Nano-Technology and CK-4 additive package are there for longevity and performance, keeping the oil cleaner longer while helping mileage and horsepower.
FR3 Friction Reducer is Hot Shot's additive for cutting friction and wear inside the engine's moving parts. It lays down a protective barrier between metal surfaces, so there's less metal-to-metal contact. Less friction means lower operating temperatures and better fuel efficiency. Hot Shot's credits FR3 with helping prevent premature engine failure by reducing wear on pistons, bearings and camshafts, which extends engine life and cuts down on maintenance. The company also says its FR3 oils hold their performance longer, which extends oil change intervals and lowers overall maintenance cost. Longer intervals are Hot Shot's claim; your owner's manual or oil life monitor is still the place to start.

Frequently asked questions
Does this oil meet Ford WSS-M2C171-F1?
Yes. Hot Shot's says its 5W-40 and 10W-30 Green Diamond Fleet oils meet Ford Specification WSS-M2C171-F1 for added wear protection on top of exceeding API CK-4. Confirm your manual also calls for the 10W-30 grade.
What does FR3 do in the oil?
FR3 is Hot Shot's patented friction reducer. It builds a barrier between metal surfaces to cut friction and wear, which Hot Shot's ties to lower operating temperatures, better fuel economy and longer engine life.
Can I stretch my oil change interval with Green Diamond?
Hot Shot's says the oil's high detergency and oxidation stability make longer drain intervals possible. Start from the interval in your owner's manual or your oil life monitor.
