Lubegard 30916 Heavy Duty Engine Protectant, 32 fl. oz.

Always add this at every oil change. Could be overkill but with a Ram 5.7L Hemi engine issues can cost you $$$$$. Much cheaper to buy this and a good full synthetic oil and filter.

Received this engine oil protectant in good order. Hope it’s good product as I will try in once I’ve done my next servicing

I test it for two car ( Honda vamus and Toyota spade and also two motorcycle BMW R18 and R nine t. Those two bike will be overheat in traffic ( heavy traffic ) in summer in Japan but after I use it for bikes it doesn’t overheat anymore and the cars engine is also work very silent . I will use it every time I change the engine oil.

UPDATE January 2017: All stated benefits still being 100% accurate, I tried this in my lawnmower (Honda 165cc engine) and it notably quieted the engine. I mean, the wife commented on it. It is also much more difficult to stall now. Same gas. Same spark plug. I'm impressed. Smoke on cold start was also eliminated.This significantly and noticeably quieted the engine operation on my 2013 Ford Explorer 2.0 Turbo, 99 Impreza Outback Sport 2.2, and 2011 Outback 3.6R Limited. All three now have zero valve noise on cold start and idle in virtual silence....with minimal cooling fan activation.Engines seem to rev more freely and there has been a .5 MPG improvement on the Explorer, a .7 MPG improvement on the Outback, and a 1MPG improvement on the Outback Sport. I'm imminently pleased. And, this was added in the proper ratio to synthetic oil (Pennzoil Platinum, PP High Mileage, and Castrol Edge Titanium Gold Bottle)....so the effects are not being minimized.I will continue to update, but I'm extremely pleased. I did not expect such a large improvement on engine smoothness across these three vehicles.

Became a fan of Lubegard transmission additive, only brand of additive I trust. I started using the engine oil protectant in all my vehicles. I cannot speak of added MPG or significant performance gains though I do notice smoother and quieter running engines. I also see less oil consumption in the vehicles treated with this additive. Wish the price was more budget friendly.
