30015 Engine Oil Protectant for Turbocharged Engines, 15 fl. oz.

Anything LubeGard is very good. I have been using their products for years!!! I also use the trans fluid and fuel treatment. I know it cost more than other products, but it is very good. You get what you pay for. It works. It makes my engine quieter and more gas mileage. It keeps the oil cleaner. I highly recommend this.

Put this Lubeguard in my brand new 2026 Jeep Cherokee hybrid with its turbocharged engine. Really smoothened everything out including acceleration.

Put the lubegard turbo oil additive in with pennzoil 0w20 ultra platinum in my 2026 nissan rogue and man the smoothness all around feel is great. Helping to protect the turbo and the engine. With all the problems Nissan has had with these rogues, you need all the help you can get. The lubegard comes highly recommended combined with the pennzoil 0w20 ultra platinum for the Rogue 1.5 liter turbo.

Lube Gard doesn’t pay me to say this… I really like their products, and have used them in many vehicles. However, if this is “snake oil,” I will gladly pay for it over and over! It had an immediate effect. I put it in my 2020 Subaru with the 2.4 turbocharged engine at the oil change; after the initial brief run and fluid check, I took it for a quick drive to run an errand. I couldn’t believe it! After starting, it didn’t sound like every other Subaru (mind you, we have several); no overt “clicking,” idle seemed smoother, engine “noises” were non-existent. Seriously? Even if it is placebo effect, I’m happy. I can’t wait to see its action for long term. Bottle is 15oz and I used 12oz vs the whole bottle, as it’s 4.5L of oil and I figured I would try the minimum effective dose.

Works as it should

If I can give a 100 stars I would. All Land Rover Discovery owners need this. Mine was lagging power and inside the cabin I would smell exhaust fumes. The dealer said it’s common on Land Rover and expensive to repair. I searched everything and found this product on Amazon. Add this to your oil change and use 93 octane gas in less than 50 miles the problem went away. My disco feels factory fresh

It is made out of plastic and half of it was spilled out. I poured it into my 2012 Mercedes c250 sedan 1.8L with turbo and I didn't notice anything different. Maybe it needs more additive but this could be snake oil as well.

Extra protection for turbo motors. I use quality oil and quality filters, but like to use this for my turbo motor. Have had great success with another lubegard product (shudder stop for transmission) which led me to this.
