Lucas Oil 10725-PK18 Octane Booster - 2 oz, Pack of 18

This octane booster really increases the octane numbers by 3. I have a Harley Davidson motorcycle that’s had the engine upgraded, it requires a minimum of 93 octane. These engines don’t run well on 91 octane and really bad on 87 octane, this is a high compression engine. Harley Davidson has their own octane booster. My engine runs better on Lucas. There are other good octane boosters but Lucas has the best price for me in this “15 ounce” , the other size bottles are more expensive per ounce

Look at your mox ratios:octane rating as compared to other trendy items that people use at the track. I've used this since Covid hit and had 2 cars that required 92 octane. You get a lot more octane from this sauce over the ither one in a metal can. It's Lucas and should speak for itself. We run this in our OHV toys and it's a significant change iver standard E-Free gas. If you must have "racing fuel" you're best to use aviation fuel which lasts much longer and costs about $3 less per gallon. Of you just want or need some hot sauce in the gas, this is the best you can buy for the money.

My 1971 car will knock with just gas alone (I only use 100% gas, no alcohol). I add one bottle to each 11 gallon fill up and I get no knocking.

Great product huge bottle and works as stated. I used half and notice the improvement of my fuel system.

This stuff really works, you can literally feel the difference, I use it in all my rides.....I just wanted to add a safety message for folks in very hot environments, I just received my delivery of two bottles, and while opening the product, while pulling the clear tab to get the top open, It spewed out in a high pressure stream....so keep tour face and eyes away from the opening if it's really hot outside..... This may also explain why sometimes when you receive this product it has leaked out into the cardboard box.... No complaints with the product at all, works like a charm....

This product works as advertised and did what I needed it to do. Another quality product from a good, honest company.

Use it in my Harley. Cams, headwork and Race tuner, etc. No pinging. I think it's worth it,,,,,,,,

My muscle car requires more octane for it to run efficiently this additive works as advertised.

Definitely gonna buy it again

لم يصلني الطلب وصلني حجم صغير جدا عن الصورة في العرض و كأني سأضعه في خزان سيارتي هذا يوضع في دباب صغير و سعره على حجمه الصغير غالي جدا و غير مبرر

Perfect for my 1998 Jeep Cherokee Laredo with a custom built racing engine including all the trimmings(K&N Air Intake, Magna-Flo Exhaust, Banks Headers, Hi-rise helix, 28lb Injectors, etc.)

this has worked wonders for my car as it has a upgraded hybrid turbo, decat downpipe full stainless steel custom exhaust, upgraded intercooler stage 2 custom map etc. no knocking/pinging car running to absolute peak spot. made a huge difference in my case.but should also make a noticeable difference in standard cars.

excelente producto
