Default Lucas oil treatment

I have been using Lucas oil upper cylinder treatment with my car and Costco 91 gasfor the last month and it seems to add a bunch of power and help the fuel economy a little. Anyone else use any fuel treatments and if so what are your results good or bad?

P.s. I only put 91 in my car; 90% of the time it's Costco gas, and if not some other top tier gasoline.

I only use Costco super, I think that's 93. Never tried fuel conditioners... do they really help when Top Tier already includes additives?

From my research they can boost octane slightly by few points.

Yes, Costco premium gas is 93 octane, at least where I live.

I have used Redline twice in my older GS and once in my current one mainly because it sat a while before it got sold and likely had bad gas in the tank but those were gas treatments to maybe clean the injectors a little. Oil/fuel treatment is not something I use often, maybe once every 4 or 5 years, using them more often is probably a waste of money.

I did use a Liqui Moly engine cleaner you add to the oil before a change and Ceratec when my 2nd Gen GS was around 100K miles, did not notice any difference honestly, fuel economy slightly improved but I mainly did it because they were on sale and was thinking they could not hurt/possibly help on a car I was planning on keeping for a long time.

I will get Liqui Moly Engine Anti Friction Oil Treatment and add some during oil changes, it is cheap and gets good ratings.

Why don't you get this as well? Must be good for a few more horses... LOL...


But seriously, those are only worth it if it makes you feel good about what you're putting in the engine. You'll find out lots more data out there that shows the benefits of those additives to be negligible or non-existent.

But like I said, if it makes you feel good, use it. I usually used Seafoam a couple of times a year, not sure if it works, but it makes me feel like I'm helping my engine out... who knows?

Unless you are having an issue with your gas or oil, I would not add anything to a modern engine.

Some older, high mileage cars might benefit from a few treatments but I'v pretty much decided there's no easy fix to anything. I've used SeaFoam to clean the intake of a 200K Tahoe, Techron in the gas from time to time and some thicker oils to quieten a noisy lifter but that's about as far as I'd consider.

Out of desperation and a reluctance to replace the rear main seal, I once tried Blue Devil and it did nothing but actually make the leak worse!

Your mileage may vary, literally, and without a controlled test environment, most of your "gains" are likely attributed to the placebo effect.

Lucas Octane Booster


Published on January 28, 2011 by VolvospeedOne tank, one bottle.





When mixed in a 100:1 ratio of fuel to additive the Lucas Octane Boosted averaged a RON reading of 101.4 and a MON rating of 91.8. Giving Lucas in a concentration of 100:1 an AKI of 96.6 when mixed with 93 pump fuel. With a ratio of 100:1 this make Lucas the most concentrated additive.

When used an a concentration of 50:1 103.1 RON was achieved with a MON of 93.5 giving it a AKI of 98.4.

To date Lucas octane booster is the only booster tested that had significant results with only one bottle in the tank. One bottle is enough to make 10 gallons of 96.6 octane out of 93.

All testing was preformed on a Shatox meter and later validated via a knock engine

No idea who the hell Volvospeed is and why they would ever be considered a trustworthy source...

https://en.wikipedia.org/wiki/Gasoline

Physical properties[edit]

Density[edit]

The density of gasoline generally ranges between 0.71 and 0.77 kg/L (719.7 kg/m3; 0.026 lb/in3; 6.073 lb/US gal; 7.29 lb/imp gal), with higher densities having a greater volume of aromatics.[47] Finished marketable gasoline is traded with a standard reference of 0.755 kg/L, and its price is escalated or de-escalated according to its actual density. Because of its low density, gasoline floats on water, and so water cannot generally be used to extinguish a gasoline fire unless applied in a fine mist.

Stability[edit]

Quality gasoline should be stable for six months if stored properly, but as gasoline is a mixture rather than a single compound, it will break down slowly over time due to the separation of the components.

Gas is a mixture, they take straight gas and mix in other components to get to a set octane. Not everything is snake oil.

Why would you care about octane booster with a Lexus luxury 4-door sedan with a V6 engine?
