The Complete Handbook of Vehicle Engine Degreasers

Finally, a handbook that treats engine degreasers as something worth understanding properly. I run a commercial fleet shop, and for years I've been choosing products by trial and error or vendor recommendations. Chapter 1 alone—explaining how surfactants actually dissolve oil at the molecular level—changed how I evaluate new products. The real-world examples (like why solvent-based products leave residue on cold days) are exactly the context missing from manufacturer sheets. I'm already using the selection framework in Chapter 3 to cut costs on our diesel fleet without sacrificing quality. This is the opposite of fluff.

This book provides solid technical information about degreasers that you won't find in typical product guides, and Chapter 1 is genuinely educational if you want to understand the chemistry. My main complaint is that some chapters feel overly detailed for someone just trying to pick the right product for occasional use—the equipment maintenance chapter could've been condensed. Still, if you're serious about this category, the depth here is valuable and rare. Recommended, especially for professionals.

I bought this expecting a straightforward 'which product to buy' guide, but it's really a deep technical handbook. Chapter 1 is thorough, but it moves fast and assumes some chemistry comfort—if you're not already familiar with pH or solvents, you might find yourself rereading. The information is accurate and practical, but the book's real payoff seems aimed more at shop owners and resellers than individual users. Worth it if that's your situation, otherwise you might get more from simpler reviews.

As someone transitioning from hobby mechanic to running a small service business, this handbook answered questions I didn't even know I had. The Chapter 1 explanation of how different degreaser types work let me stop guessing about product selection and start understanding the actual tradeoffs. The troubleshooting section kept me from wasting money on the wrong equipment fixes, and Chapter 6 on business opportunities is exactly the real-world market context I needed. Highly recommend if you're treating this as more than a one-time purchase.

Solid reference work. Chapter 1 explains the mechanics well enough, though the writing is dense in places and could benefit from a diagram or two. I found the specifications chapter useful for comparing datasheets, but felt the FAQ section didn't go deep enough into some edge cases I face regularly with heavy-duty equipment. Good foundation if you're new to the category, but experienced pros might find limited new ground. Still worth having on the shelf for reference.
