### ⭐⭐⭐⭐ Be assertive on how and what car you use it on.
*by T***L on 13 February 2023*

I have a BMW F10 520d. Was extremely skeptical about using this at first. Well, I took a chance after doing some good quality research. Yes, this can be used on a BMW diesel engine cars or any other as such for that matter, but be mindful of what to do next. Okay, so I poured the entire CAN into the fuel tank, refueling in with over 30-40L diesel in. Drove my car on the highway for about 90-100 kms at a constant speed above 80kmph, letting the DPF regen kick in and such that the mixture throttles through the engine, the injectors. Result: Uff, have to say. Noted world of a difference after using this. There's far more refinement in the engine, smoother, leaner power delivery, throttle response, and better milage. Epic. This is absolutely a very good product. Tip: CHANGE the fuel filter after you utilize this product post your highway run and before refueling your car again. It's important that you do so. It's not required to carry out this purge process frequently. The process of Purge can be done every 30,000-40,000 kms. Be advised: DO NOT use any other additives to older BMW engines. They are not meant for anything else to go in. Purge is the only thing that's safe to use as far as it goes. As for more pro-tip: The thumb rule for diesel vehicles is the right oil change intervals, highway runs, paying attention to your cars behavior, and taking care of your vehicle. Hence do keep your car's intake manifold clean, do a frequent highway run for DPF regen, and engine oil, filters service intervals below every 10k kms. Yes, I definitely recommend this for any Diesel vehicle. It works really well and like a charm. I totally see the difference in how refined my car engine runs now. LiquiMoly Purge is totally worth it. LiquiMoly is just epic and on another level for its quality products. They are renowned pioneers in the automotive industry, formulating such products. Especially their engine oil. Hope you find this helpful. Thank you.
