However, I was pleasantly surprised with the results! Research shows that the highest amount of wear in a petrol engine occurs at the uppermost parts of the cylinder and piston, during cold starts. The product was used on my 2014 Royal Enfield Continental GT 535, in Kolkata, starting in the last week of Feb, '23. The bike now has just under 29000 Kms on the odometer. I mix 2 ml of Lucas/litre of regular petrol (using a syringe) Benefit #1 - Fuel Economy Increase (city-riding only, no highway) AFTER using Lucas - 29.13 Kms/l (403.7 Kms for 13.86 litres of petrol - just over one, full tank) Before using Lucas - 27.34 Kms/l (388.2 Kms for 14.2 litres of petrol - just over one, full tank) Benefit #2 - Emissions' Decrease (Bike ridden for about 20 mins before each test) AFTER using Lucas: CO - 0.18; HC - 11 (lowest values EVER, test date - 24.05.2023) Before using Lucas: CO - 0.56; HC - 28 (test date - 25.11.2022) Benefit #3 - Reduced Vibrations and Engine-Sound Volume Engine sounds a little quieter. Vibes have reduced by, maybe, 10%. I should have objectively measured this using a mobile-phone app, but forgot to do so before using the product. Hence, no point doing an 'after' either. Benefit #4 - Increased Acceleration The bike feels like it pulls, maybe, 5-6% harder than before. Again, no objective measurement. Highly recommended to those who want to make their vehicles last longer than average! Review: Awesome results. - Unexpected results with this product. I used in 3 cars & performance of car after using this liquid is awesome. Wordless. I mean car's milage increased 4-5 kms p/l. Pickup increased 20%. Engine noise reduced 25%. Awesome results. I am going to purchase big packing 4 liters. Thanks Lucas. ## Features - Upper Cylinder Lubrication - Injector Cleaner - Capacity: 32 Oz ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000ARPVOI | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #12,550 in Car & Motorbike ( See Top 100 in Car & Motorbike ) #78 in Engine Oils for Cars | | Brand | Lucas Oil | | Brand Name | Lucas Oil | | Compatible with Vehicle Type | Car, Truck, Motorcycle | | Container Type | Bottle | | Country of Origin | USA | | Customer Reviews | 4.7 out of 5 stars 7,067 Reviews | | Global Trade Identification Number | 00049807100032 | | Item Weight | 898 Grams | | Liquid Volume | 1 Quarts | | Manufacturer Part Number | 10003 | | Model | LUC10003 | | Number of Packs | 1 | | Package Information | Bottle | | Size | 1 quart | | UPC | 049807800031 049807400033 049807100032 | | Vehicle Service Type | Car, Truck, Motorcycle | ## Product Details - **Brand:** Lucas Oil - **Liquid Volume:** 1 Quarts - **Package Information:** Bottle - **UPC:** 049807800031 049807400033 049807100032 - **Vehicle Service Type:** Car, Truck, Motorcycle ## Images ![Lucas 10003 Upper Cylinder Lubrication & Injector Cleaner 32 oz - Image 1](https://m.media-amazon.com/images/I/616euPEi4YL.jpg) ![Lucas 10003 Upper Cylinder Lubrication & Injector Cleaner 32 oz - Image 2](https://m.media-amazon.com/images/I/61vQUf40JYL.jpg) ![Lucas 10003 Upper Cylinder Lubrication & Injector Cleaner 32 oz - Image 3](https://m.media-amazon.com/images/I/81LuFRhUHdL.jpg) ![Lucas 10003 Upper Cylinder Lubrication & Injector Cleaner 32 oz - Image 4](https://m.media-amazon.com/images/I/81mEYRJiobL.jpg) ![Lucas 10003 Upper Cylinder Lubrication & Injector Cleaner 32 oz - Image 5](https://m.media-amazon.com/images/I/81lj2Vje3vL.jpg) ## Questions & Answers **Q: Will gas mileage increase** A: I drive (and now use this in) a 1996 Toyota 4Runner. Prior to its use I'd averaged 17mpg, then performed a replacement on plugs, wires, and air filter (upgrading to a K&N); in addition to cleaning the MAF and throttle body (all on my own, mind you!). I now average anywhere between 19.5 (city) and just under 25 (highway). I'm not sure just how much of a fuel increase can be contributed to this product, but I no longer go without it! **Q: Would keeping this in the car in hot Texas heat be an issue?** A: OF COARCE ITS A DANGEROUS ISSUE !! Storing any flamable liquid in a car is very dangerouse , especially a hot car !! you put yourself at risk of combustion from the heat & also combustion if you get in a accident !! buy a tiny bottle of lucas fuel additive , its about 5.5 oz.s !! fill that up and insulate it in trunk to keep it cool . then when you fill up ? you will have a bottle ready to put in your tank !! instead of hauling around a gallon of the stuff . **Q: Whats difference between this and the fuel treatment 5 oz** A: Their is no difference other than the packaging **Q: Will it help remove P0420 code?** A: 2 bottles of Lucas oil, one gas refill apart, helped with my P0420 Code on Infiniti QX60 engine light. With the 2nd bottle, the light was gone. It worked like a charm. I will continue to keep the fuel tank clean moving forward. Tip : don't wait for the fuel tank to be completely empty before you refill. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quite Impressive! *by A***E on 2 June 2023* The purpose of using this product for me was SOLELY to preserve and increase engine life.

The consistency of the liquid is thicker & much different from the additives with almost kerosene like liquid.
