Review: So far so good in both cars! - I bought this as I have an old classic Beetle that needs a fuel conditioner as we can only get E10 now in Ireland. Seems ok in the Beetle so far! I've recently started using it in my Toyota hybrid where my fuel economy had really fallen over the past year. I initially blamed a new roof rack but then realised the fuel had changed to E10. I've only used it twice on 2 full tanks of petrol. Fuel economy is almost back to where it was pre-E10 fuel. So it's clearly doing something positive. As mentioned, there's no real way to measure when pouring this into the car, so I just use a small 30ml kitchen container & that works perfectly.
Review: E10 killed my car's performance & M.P.G. - This MIRACULOUSLY restored both to previous E5 levels. - When E5 was the 'standard' unleaded fuel my trip computer would show a range of 470 - 480 miles on a full tank. In real life I would actually get 42 - 44 to the (U.K. Imperial) gallon around town, or 48 - 52 on a longer haul trip. Enter E10 as the new 'standard' unleaded & by the time it came to the third full tank the trip computer was showing a range of 400 miles, 33 - 35 around town & 40 - 42 on the longer journeys. The car was sluggish in response to the accelerator & at times sounded a bit rough. Did a bit of research & found this product was well thought of in the U.S. & was much better value than some of the U.K. brands that were jumping on the new U.K. E10 fuel additive bandwagon. Action:- Put 100ml of this into half full tank & topped up to full (50ltrs). This was approx. a 25% overdose, but for a first treatment would not do any harm. Trip computer showed expected range of 400 miles, same as previous full tanks. Result:- Two days & 28 miles later the Trip computer was showing 435 miles range remaining. The car is running much more smoothly, quieter & responding to the accelerator much better than it had been for the last couple of months. Now 260 miles since filling up & using this treatment with computer showing 215 miles remaining & M.P.G. of 43.3 so far on this tank full. THE NUMBERS SPEAK FOR THEMSELVES! IMPORTANT POINTS TO NOTE:- BEWARE - All measurements on the bottle refer to U.S. standards & are very different to the old U.K. Imperial measurements of fluid ounces, pints & gallons. A U.S. pint & gallon are both much less that the old Imperial pint & gallon. The important thing to understand is the mixing ratio which is 1:640 by my calculations, but this is not stated on any of Lucas Oil's literature or data sheets that I can find. At the bottom of the listing on desertcart, in the product description section, it states 30ml of product will treat 18.9 litres of petrol. This description is almost spot on for the 1:640 dilution ratio. BOTTLE SHAPE & VOLUME MARKINGS ON LABEL - The shape & size of the bottle makes it impractical to pour straight from the bottle into the tank without major mess & spillage thus no accuracy to the volume actually used. The volume markings on the label are basically useless due to the curvature of the shoulder of the bottle. A more accurate & controlled method of measurement & actually getting it into the tank would be very helpful. MY SOLUTION:- I use a syringe (various sizes from desertcart) intended for measurements in the lab or feeding animals etc., and a length of clear P.V.C. tube, normally used as airline for aquariums (various sizes, again from desertcart) attached. Fill the syringe with the required volume of treatment, attach to about 33cm of tube, remove petrol filler cap & push tube past the spring loaded plate at the top of the tank filler, inject treatment into tank, remove syringe from tube & refill syringe with air, re-attach to tube & blow last of treatment into tank, remove tube & syringe from tank & replace filler cap. This works well for me and is much safer than messing around with cans of fuel. COSTINGS:- Bottle of product cost under £12 & will treat 6.5 x 42 litre tank fills. Lets say £2 per tank fill. Extra mileage per tank with this stuff will be between 50 - 60 with better performance & extra protection to the car fuel system & engine. £2 for an extra 50 miles!!! No brainer!!!

## Questions & Answers

**Q: Is this okay for a carburettor engine**
A: I'm using it in a 4 stroke petrol lawnmower. and to protect the fuel system of a seldom-used emergency generator.

Seems OK - the reason I bought it was to stop the Carburettor from gumming up, and to extend the storage life of the new high ethanol fuels, E10.
Quite happy so far no probs after 3 months of use.

**Q: Been using lead replacement so far on my 50 year old car, Is this designed to be used together with a lead replacement, or as an alternative?**
A: It's to aid the difference between the old E5 petrol to the new E10 that most garages sell as unleaded. ( If you open a carpetrol filler flap pre 2020 it will probably say use E5 95ron ) I would assume you would have to use both the lead and ethanol replacement but a mechanic that deals with vintage ( lead based petrol) vehicles, would be more an expert and you would be advised to ask them about that.

**Q: Does this protect rubber components in the fuel system?**
A: Yes, it does! Thank you.

**Q: Can I use this in a 2016 ford fiesta 1.2 which has a catalytic converter without harming the Cat**
A: Answering another question in this list, the manufacturer states that the product will not damage a catalytic converter. Some other customers have also said the same. That's all I have to go on.
