300 life expectancy.
Im curious. For everyone here whose said they ran their 300 out of oil. Do they not use hydraulic lifters? My wife ran my jeeps 4.0 I6 out of oil and it promptly shut off, due to the lifters being out of oil and basically the engine suffocated. Did the 300's not shut off? I never have, nor plan to, run my 300 out of oil and find out. Just wondering if it happened to you guys.
Hehe yes I own two I-6's and love them both!!

I have a 4x4 F-150 pick up, 4.9 6L engine, and has 230K miles, with the original engine, it run smooth, no noise, it is standard, no oil consumption, no oil at the air box, I have not test for compression, but has one problem, the engine start easy with cool wheater, the engine need to be warm up to prior running other way will not stand the engine ( go off) , I think is a carburator problem, also if the engine is warm is not easy to fire it. I appreciate if anyone knows this knid the problem and give some help.

My 91 F150 4.9 now has 193,000+ miles on it. Bought it with 73,000 on it. It must have a limiter or something on it because it will not rev over about 31 or 3200 when accelerating. Thats ok though because most of my speed is gained in second gear (E40D) at between 1500 and 2500 RPM's. It uses maybe a half a quart of oil in 3000 miles and I mean maybe. It is a great truck and after seeing what my buddy went through to do a repair on his 302 I will keep my 6 any day.

The 302 is a good motor but because of it's short stroke, it lacks bottom end torque that the ol 300 just pours out. 302s are much better off in a car. Also the 302s don't hold oil pressure very long and you can't beat on em as hard as you can a 300.

i have a 1965 Mercury pickup with a 300 that was abused pretty bad, racked up about 380K miles, stock 4:10 rear end made 60Mph highway running take about 4200RPM.. i recently pulled the engine out for a hotrod rebuild and was quite shocked at how everything looked.. engine ran smooth as new, great power..
but.. check the link to a pic of the pistons i have included.. and yes.. thats how the oil in the poor 300 looked!

I just bought a 83 f100 i300 4x2 and it's got 255,000miles on it and it's never had any engine or head work on it.
I know because it's a one owner before me.
My mate has a f150 4x4 which he uses offroad and once he punctured his sump on a rock and he had to drive it 155 k's/100miles before he could get it fixed, that was two years ago and the only problem he's had from it is that it now blow a tiny amount of smoke when it's cold.

Bottom line is the 300 is probably the best engine Ford has ever made. With little to no service it will faithfully serve anyone's needs. It's stout 7 main bearing block and nearly indestructable bottom end will stand up to the abuse and keep on truckin'. I would take the ol 300 six over any small block Ford, Chevy, or Dodge.

BLACK PICUP...
The older 300s were notorious for carburetor problems. I would start by replacing the fuel filter. If that does'nt fix it, try running some Deep Creep in there, spray it down the inside of the carb and let it sit for about 15 minutes. Then start the truck and let it run for 10 to 15 minutes, you will get a lot of smoke from the exhaust that is normal. Deep Creep is amzing stuff it cleans the inside of the carb, intake manifold, valves, combustion chambers, plugs, and the tops of the pistons. The smoke coming form the tailpipe is all the crap and crud burning off as the engine runs it will clear up. If you still have that running problem you may have a choke problem or it needs to be adjusted, also the float may be hanging up a little in the fuel bowl. To fix this take a light ball peen hammer tap the top and sides of the carb body. While your in there check the carb mounting nuts to make sure they are tight.
Good luck!

Thanks a lot Pkupman82, unfortunately, I cannot find the stuff you recommend me ( Deep Creep), I am living in Venezuela ( no place for good spare parts and mechanic) , but that stuff would be very good to eliminate hot spots in the engine so it can reduce or prevent knocking ( auto ignition) in the engine, some time you notice it when you turn the engine off and it still running for short while. The choke and/or float topic will make more sence to me, one thing could be the spiral spring that got old and has not the enough spring effect ( may be), I have no idea how to test it, and the float ( level of the fuel inside of the carb) also could be one, neither I do not have the idea where the level should be, I do not know if this carb has a neddle to rich or poor the mixture for idle regimen, ( where those needle are placed?, if there is any. This pickup I got it from my older brother, that is why I do not know this engine well. I appreciate any of your help, thank in advance.

BLACK PICUP...The carb on your truck does have an air mixture screw on the base plate of the carb. I can't remember exactly where right off. I can't go out to check because I am stationed in Okinawa Japan for 6 more months (USMC) I miss my trucks, getting tired of working on HMMWVs. Any way give the float a try and also you could play with the air screw and see what happes. Oh and yes Deep Creep will work in any kind of engine including your lawn mower.
