Griot's Garage Engine Cleaner for Car, Motorcycle, Boat, RV, and Truck, Oil, Dirt, and Grime Remover, 11158, One Gallon

Good, high quality product. Made my dirty engine bay look new again with a good amount sprayed on, let it sit, and agitate where needed. Griots rocks!

Griot’s Garage Engine Cleaner truly delivers a premium detailing experience. The formula is powerful enough to break down years of built-up grease, oil residue, and road grime, yet it feels thoughtfully engineered to be safe on plastics, rubber hoses, and painted components when used as directed. What impressed me most is how efficiently it works — a light mist, brief dwell time, and agitation with a soft brush is usually all it takes. It rinses clean without leaving behind a chalky residue or artificial shine. Instead, the engine bay looks naturally refreshed and factory-clean. The spray pattern is consistent and controlled, making application precise even in tight spaces. For anyone serious about maintaining their vehicle beyond just the exterior paint, this product elevates the standard. It’s a reliable addition to any enthusiast’s detailing arsenal.

If cleanliness is next to godliness, then Griot’s Garage Engine Cleaner might just be holy water for your greasy lawn mower, leaky engine bay, or any surface that's seen better (less oily) days. Used it on a mower that looked like it lost a fight with a deep fryer—came out clean and smugly ready to mow in polite society again. It's also a champ under the hood: spray it on, let it sit, rinse, and boom—your engine's suddenly ready for a photoshoot. As expected with Griot’s, the quality is top-tier. It’s like the brand has a secret pact to never disappoint. The only gripe? If you want their full lineup, you might have to order directly from their site, and unless you’re buying in bulk, you’ll be paying for shipping. Pros: Cuts through oil and grime like it’s offended by the mess Excellent for lawn equipment, engines, and your dignity Griot’s consistent, high-quality formula Available in a generous gallon size—enough for your car and your neighbor’s Cons: The full product range isn't always available on Amazon Buying direct from Griot’s requires a minimum spend for free shipping Final Verdict: Whether you’re degreasing a car, a mower, or just your pride after ignoring that oil leak for too long, Griot’s Engine Cleaner gets the job done—with style and suds to spare.

Review of Griot's Garage 11158 Engine Cleaner Gallon 128 Fl Oz (Pack of 1) @ $22.98 After reviewing several products of this nature, I opted to try this one. This is my first time using an engine cleaner. I purchased some of their engine bay dressing as well and have included before and after photos. The middle photo is after using just the cleaner but before the dressing. This was used on a 2002 Ford Taurus. It doesn’t have a lot of miles on it for the year (about 138,000), but the previous owners lived on a gravel road, and it was subjected to a lot of dirt and dust. It will then be used to clean my 2016 F150 that has only 81,000 miles on it, and I had plenty of product left to do this vehicle when I am ready. This appears to be made in the USA. They offer a 100% guarantee. Both are pluses to me. It arrived in good condition and intact with no leaking. It does not come with a spray bottle or any type of spraying mechanism. The ad on Amazon shows a Griot spray bottle, but none comes with this. This was a negative to me. This is NOT a concentrate that you mix with water to make it go farther. I suppose one could dilute it some on an engine that did not have much dirt, but I chose to use it full strength. I used an old gallon-sized home pest control bottle with a built-in pump sprayer to apply this product. The product is simple enough to use and applies easily. It says to spray it on, agitate and wipe clean. It dries quickly, especially on a windy day, so I had to re-spray some areas. I’m of the opinion that perhaps some Dawn dish soap mixed with water might have done as well, but I chose to try this since it is made specifically for this purpose. I will let the photos speak for themselves regarding the results. All in all, I am pleased. I deducted 1 star as I felt advertising a spray bottle with the name brand on it and not including it is misleading.

I've used this product on a car engine and several riding mowers that were leaking oil. The degreaser didn't have a problem removing the grease and oil . Engine looks great after use. Sorry no before and after photo.

Works…..I am a groits fan, all their stuff works.

Great product, I was disappointed when I went to use it someone had already punctured safety seal to use it but then returned it. They should check theses things before sending out

This stuff is amazing for making an engine bay look great. I cleaned up all my vehicle engine bays with it and followed with the engine bay dressing. Vehicles look like they just came off the showroom floor

I used this product to clean my Porsche 996 engine which had not been done in the last 9 years. Believe it or not I only used about 5 fluid ounces to clean the whole engine. I used a hand pump sprayer to apply, some occasional brushing to clean some really mucky areas, and an air pump sprayer (the type you would use for applying weed killer) with fresh water to rinse. The advantage of the air pump sprayers is you can apply a very fine spray of water to get into difficult areas of the engine bay. Griot's product really cut through the grease and grime really well. Often, I only needed to rinse with water to get components clean. I completed the engine clean with Griot's Vinyl and Rubber Dressing.

is a very good product and did an excellent job of cleaning my engine bay on my car.

best engine cleaner so far, easy to apply ,,,when you rinse down and let it dry you will be pleasantly surprised ,,,engine looks like ne
