Good day to everyone,
My question is are there any people out there
that use oil and fuel addtives like MARVEL MYSTERY OIL,AND
LUCAS HD OIL STABILIZER. LUCAS FUEL TREATMENT,SEAFOAM and the list go's on with great success.
cause again I pull the sparkplugs looked in the sparkplug holes with flashlight top of pistons are very black with carbon. should i pour seafoam down the carb and let set for a while then crank up for smoke screen show or just pour sonething in tank to clean carbon slowly if a product like that is strong enough on the self at the autoparts store
thanks stovebolt

I have used seafoam thru the intake vacuum tube while running the engine at high idle, flooding the cylinder ports carefully, shut down and let it sit for 30 minutes. Then fire up the engine to clear the carbon. Seemed to improve idle and performance. I am a firm believer that if you don't use the cheapest gas and put in a quality tier 1 fuel, it cleans the cylinders and valves much better than cheap gasoline from the no name brands.

Hey grog11, you mean top tier like chevron with techron, shell with nitrogen enriched,marathon with stp,ETC.At my work we have gas and diesel to run equipment on the yard. The other day when our fuel delivery man was filling our tanks I asked him about the addtives they add to different gas stations listed above. He said when they pick up a truck load of fuel to be delivery that they only mix 10 to 20 oz of addtive to 1000 gals of fuel per truck. That doesn't seem much at dilute ratio.But i still use top teir gas stations.there was this old timer that was machine shop owner he said 89 octane was better to run than 87 .He could tell a cyl head carbon build up from using 87 compare to 89 or 93 octane fuel.
I know using 93 in my car is a waste of money being its not high compression.and the factory called for 87 fuel.but now with today fuel with ethnaol cars seem to run like crap and use more fuel cause of ethnaol 10% crap and 90% gasoline.

THANKS

I too think that 89 octane does perform better, and the old timer was probably right about less carbon building up.

Top tier fuel standards list, are ones that have been approved by the automakers to meet their standards, what ever they are..
Does anybody know exactly what amount of additives would meet automakers standards?

[grog11]

Top Tier Detergent Gasoline
TOP TIER Detergent Gasoline is the premier standard for gasoline performance. Six of the world's top automakers, BMW, General Motors, Honda, Toyota, Volkswagen and Audi recognize that the current EPA minimum detergent requirements do not go far enough to ensure optimal engine performance.
Since the minimum additive performance standards were first established by EPA in 1995, most gasoline marketers have actually reduced the concentration level of detergent additive in their gasoline by up to 50%. As a result, the ability of a vehicle to maintain stringent Tier 2 emission standards have been hampered, leading to engine deposits which can have a big impact on in-use emissions and driver satisfaction.
These automakers have raised the bar. TOP TIER Detergent Gasoline help drivers avoid lower quality gasoline which can leave deposits on critical engine parts, which reduces engine performance. That's something both drivers and automakers want to avoid.

Well said,
But i do think the oil companies and gas stations are in bed with the car companies.Cause you can't have one with out the other.like for example back in the 1960 to late eighties. the best mpg you could get out of a v-8 was 15mpg,but I know with these newer cars are getting 20 to 24 mpg in some cases.but i think back in the old days the car companies knew something they did not want the public to know.One of mine uncles back in the sixties bought a brand new dodge dart slant six motor. That got 26 mpg new.a year later he got a letter from dodge saying there was a recall on the carb for his car.So he took it to the dealer. they swap out the carb after that the best mpg he got was 16 to 17mpg. some say it was a high mileage carb dodge was testing.the past is very haunting.I have heard stories on the 100 mpg carb.saying that the auto and oil companies snuffed
people out that didn't sell out to them.It's a big money game. back in the first gulf war you could get gasoline for 99 cent gallon at racetrac
stations those day our gone forever.

whats the best fuel mileage has anyone got in a fairmont 3.3 6cyl.auto trans.the specs say 24 hwy and 18 city with combine 20mpg cause of the age and mileage on mine. i getting about 17.5 to 18.5 on the hwy driving 6o miles a day around trip to work 5 days a week.do you think the wagon get less than sedan?

Sea foam is the only thing I use excep I add a quart of trans. flud to the crankcase onece in a while if my lifters get a little noisey.

[mark v]

Really if the gas station has 87 89 or 93 octane the 89 is really a blend of the 87 tank and 93 tank so the 89 is just a mix of 87/93 gas so are you really getting a better fuel?

Still if your engine is running properly the 87 will perform just the same a 89 (you will not notice the increase of 2 octane), it is just a mental thought that makes you think the 89 is better. Just like waxing and cleaning your car seems to make it faster!

[stovebolt]

someone, once said that marvel mystery oil is blend of trans fluid with a
wintergreen scent

[mark v]

If you THINK Lucas is the best read here.

What about Additives?

Wait for the page to load. Funny how he removed all of this from his site, did he sell out?

[stovebolt]

so you think lucas oil additive and stp oil treatment are same thickest

stp oil treatment $3.00
lucas oil product $12.00 for regular
$20.00 for the super slick stuff

[Jonzo77]

marvel mystery oil is awesome! they've been around for decades, and old hot rodders swear by it. that's good enough for me to use it...

[stovebolt]

hey,jonzo77
Going to give marvel mystery oil a try! website said could increase mpg. might help or not gotten fill up for the week commute.
bought a bottle bout a hour ago.add 8oz to 16 gallons of 89 octane
gasoline with no enthanol at $3.20 gal

What about Ford's recommending only 87 octane in '08 Escape 3.0L V6, regardless of altitude? A Flying J spokesman told an SLC TV reporter that octane at higher altitudes did not need to be as high as at lower altitudes. Why would Ford disagree with that?

The engine will have less compression at higher altitudes, which will mean it could resist detonation with lower octane fuel, but 87 is a s low as it goes. I don't think Ford engineers disagree with the Flying J guy, it is just that you can't buy lower octane than 87, unless you add water and leave it sit for a year, or so.

What do the spark plugs look like? I think the spark plugs might be a better indicator of combustion efficiency than the piston crowns. I know that with high perf. two stroke engines we look for a nice even layer of carbon on the top of the piston with small wash areas at the transfer ports and maybe even at the exhaust port. An overly rich fuel set up will cause the top of the piston to be washed clean by the excessive fuel. This piston wash is key indicator in carb tuning.

Wet and lumpy carbon deposits on your piston tops would be bad, but dry, even carbon may not be bad at all. You also might be more concerned with carbon build up in the intake tact, valve stems and intake port. Heavy carbon on the piston would indicate carbon on the head and the valves. Ford made a Top End engine cleaner that some old mechanics told me was the best stuff around. The type of stuff you pour down the intake with the engine running, then dump the last half of the can to stall the engine. You let it sit for 20 minutes and then restart and try to escape the huge cloud of heavy smoke the comes out the tail pipe.

This technique might not be good for catalytic converters, but I do not know for sure. When I used it once on my old XL it lowered the cylinder compression readings by 10 lbs across the board, so I think it cleaned some crap out of there. Some people also use water, which steam cleans the top end.

[stovebolt]

all the spark plugs are a rusty copper color and hard carbon,or deposit on the electrode. i have to take plugs out every other week to clean with wire brush and regap cause start having a slight cyl misfire. on few of the plugs the deposit cause the gap to be bridged, someone told me the deposit is from a fuel additive in most gas station. or it could be the enthnol fuel now is so different than in 1981 would you say.

You can buy 85 octane in Colorado....just saying ...lol
