I admit I was impressed. My 2005 Nissan Titan oil pressure always stayed low and yes I kept the oil full. But after adding this stuff to my oil the engine became somewhat noticeably quieter and my oil pressure now stays normal all the time. Now to be fair I didn’t buy it thinking it would cure my low oil pressure problem. I actually thought that was the sensor going bad possibly. But the quietness and smoothness of the motor is impressive to me. Yes this stuff is expensive to a degree but I say it is worth it. Now there are a few claims that others have had a sludge like build up in their oil pan. Now I can’t testify to that as of yet. For I’ve only had it in my oil for two months now. I plan on changing the oil soon anyway so the contents of this additive should go out with the oil with minimal residue left in the engine. I want to evaluate how long possibly the residual can if at all keep the engine smooth after the majority has been taken out. If I find the engine gets louder in some way I will more then likely try another bottle and leave it in longer. I am weary that a sludge or thickness could build up. Of course the few claims I’ve read are definitive proof that other factors of these people’s engines could have played a role in their problem in the oil pan. So the jury is still out on the long term effect of the oil. I will more then likely sell the truck before I have a chance in the future to determine long term results. But for now I have to say I’m very impressed with it. Review: An additive that isn’t just motor honey - After watching a few videos on this product I thought I would give it a try. Keep in mind a motor in good condition really doesn’t require any sort of an additive but on a higher mileage car, or a car you do not know the history of maintenance on, this product promises some results that could provide as much benifit if not more, than mystery oil or “oil treatments “. I used it to clean and lubricate an engine that ran well but was making some noises that could be friction related. It is too soon to report the results but if the videos prove to be true I can’t see any harm and potentially a great benefit by using the oil if the valve train does get cleaned up some along with the lifter bores. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07H9K62X3 | | Brand | BestLine Lubricants | | Customer Reviews | 4.5 4.5 out of 5 stars (251) | | Date First Available | November 18, 2019 | | Is Discontinued By Manufacturer | No | | Item Weight | 1.25 pounds | | Item model number | 8542054240 | | Manufacturer | BestLine Superior Lubricants | | Manufacturer Part Number | 853796001184 | | Product Dimensions | 4 x 3 x 7 inches | ## Images ![BestLine Premium Synthetic Engine Treatment - Image 1](https://m.media-amazon.com/images/I/617cFWgK1xL.jpg) ![BestLine Premium Synthetic Engine Treatment - Image 2](https://m.media-amazon.com/images/I/61EGxu0BrNL.jpg) ![BestLine Premium Synthetic Engine Treatment - Image 3](https://m.media-amazon.com/images/I/61qSi9TbtNL.jpg) ![BestLine Premium Synthetic Engine Treatment - Image 4](https://m.media-amazon.com/images/I/61xti+HwFEL.jpg) ![BestLine Premium Synthetic Engine Treatment - Image 5](https://m.media-amazon.com/images/I/61ykC4k13fL.jpg) ## Questions & Answers **Q: Can I use it in gasoline truck?** A: Hi and thank you for reaching out to us. Yes, this HP Engine treatment is for a gasoline vehicle. **Q: Can it be used in ford turbocharged 4cyl** A: Hi, it will work very well and will provide extra protection for all components. **Q: I have chevy suv, suffers from deteriorating oil suction o-ring. will this help seal it back up?** A: Hi, good question and the answer is our BestLine Engine Treatment will clean the rings and smooth the cylinder walls. Most of the time our customers tell us it reduces the oil burn by 90%. It's an inexpensive way to protect the motor and probably reduce the oil burn rate. **Q: Is this also for engine coating** A: I don’t know what you mean by engine coating, but watch a YouTube video or two on this product and it will answer all your questions. I’m sold on it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ So far so good *by M***E on October 11, 2019* Ok so I watched project farms do a YouTube video on this stuff. I admit I was impressed.

Keep in mind a motor in good condition really doesn’t require any sort of an additive but on a higher mileage car, or a car you do not know the history of maintenance on, this product promises some results that could provide as much benifit if not more, than mystery oil or “oil treatments “.

But my engine already runs smoothly. It's main purpose is to prevent dry starts & protect the engine if you start to lose oil. It will give you a bit of a window to get to a shop or to get more oil in case of catastrophic oil loss. Best line & Motorkote are the best for these purposes. Both protecting & somewhat preventing dry starts & protecting the engine if it starts burning oil, losing oil slowly, or losing oil rapidly. On engines with more sludge/buildup or are experiencing a bit of lifter tick or valve noise, or just sound a bit rough, this (& Motorkote Hyper Lube) will help make your engine run a bit better & smoother resulting in less engine noise & better fuel economy. It all depends on what the starting condition is. If it's an engine in already great shape, that runs & drives well, then this (along with frequent oil and filter changes) will help keep it protected & running well & you may not notice a huge difference. But if the engine is in rough shape, then I highly suggest doing a gentle (very gentle) engine flush with an oil & filter change twice (once to remove the main crud, & the 2nd to get the rest out. It's cheaper than a new engine) with cheaper oil & filter on the first change, then put this (Best Line or Motorkote) in with a high grade oil & filter that is appropriate for your vehicle & you should notice a huge difference all around in how the engine performs. It's worth the time, effort, & money to do it properly. Your engine will thank you! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/86283884-bestline-premium-synthetic-engine-treatment](https://www.desertcart.sk/products/86283884-bestline-premium-synthetic-engine-treatment) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-07*
