IMO....wasting money.
Lucas is good stuff, but can be tough on an old oil pump to push. However, I so no reason to not use it really.
The "high milage" oils do have different additives over regular oil, but realistically not really something that can be proven or has been shown probven in anything I have ever read.
As far as engine restorer..... hehe I equate that stuff to "mechanic in a bottle", and I do not beleive in it. No bottle has ever fixed an issue in my car. Only wrenches.

If the car is still in good repair otherwise....start looking for a good low milage motor and when this one dies, swap it out. Then keep on truckin.

 

if the cars are on their last leg.. then i say try everything on the shelf...

as far as an additive with oil on a regular basis.. no issues with the Lucas oil add.. its nice stuff.. but if you use good quality oil that is spec for your car anyways.. its really a moot point.

semi true. i used a bottle to fix a rad leak and have no issues.

 

thanks for the replies, the reason i asked was because i spoke with a mechanic i used to work with and he said if your valve seals are leaking to use lucas and if its the rings to use the restorer, i know forsure the seals are leaking (puffs blue at startup), im not 100% but i think the rings on cyl #3 are starting to go cuz the spark plug gets carbon covered after about 2-4 weeks of regular driving, and also i got lucky enough one day when i was cleaning the plug that the piston was at tdc and it looked dirty, black and brown from what i could see from the plug opening.
any thoughts would be helpful.

hahahahahahahahahahahahahahahahahahaha <-----equal to the amount of hours you will spend on the replacing of your heatercore someday and the reduced water jacket sizes that will cause premature engine failure.

Stop leaks are the equivelent of using duct tape on the shattered windshield. They are sold to people who are to ignorant to fix their cars right. Unless you mean the two tube plastic paste to patch the hole. Those are not going to "harm" anything, but end up leaking in the end someday.
I am not trying to bag on you but even I, the greatest cheapo fixer I have even known, won't use it, it must be bad.

exactly. those things cause more harm then good. i use to work in a shop and dealt with many "bottle fixes". person had a leaking thermostat housing, so they added stop leak. car started leaking again and brought it in. stuff gummed up the radiator and thermostat (stuck open) so instead of a $50 repair, it came to like $600.

there is no need for lucas or restore. its more harm then help. there are only two types of oil that are worth using, conventional and full synthetic. just run a good api approved oil.

 

you guys didnt read very well.. the engine already has leaking valve seals.. adding an oil stabilizer/thickener isnt going to harm squat.

straight lucas.. sure.. its like 70wt.

and if youre rings are so shot that youre trying Engine Restore.. then what does it matter what the crap does.. youre going to end up rebuilding/replacing the engine either way.

as for coolant.. i agree to a point. ive seen alot of those sealant in a bottle items gum up alot of heater cores and radiators when used excessively.. as directed, not really too many issues.

however id rather see fluid leaks fixed correctly. rings and bearings.. on an escort engine it wont matter..its so cheap to replace the engine anyways.

 

my cooling system is fine, its just the one cyl that dirtys the plug, it runs fine, a little rough at idle but nothing to bad, a compression test would give me a better idea but no guage, and could the valve seals leak enough to dirty the plug & piston that bad? and the colour of the other 3 plugs are white and a light tan/brown on the plugs, this normal?

 

sounds pretty normal to me.. i mean that one cyl fouling the plug .. or does it just alter its color? if its not fouling the plug, id leave everything be.. go on like normal.

if it IS fouling the plug, then id take a compression test reading.. see what that shows.

 

if i leave the plug in long enough without cleaning it, it starts to have carbon build up but if i clean it once every 2 weeks or so its just black to dark brown, and when i pull the plug after its been in the motor for over 2 weeks theres oil on the threads

 

I just discovered that its doing the same thing on cyl #1 but not as quickly, doesn't bad spark plug wires or a bad coil also cause plug fouling?

 

I have witnessed lucus work.

A friend of mine has a 70s f100 puckup with a 410 marauder, would run rough as hell and he couldent figure out why. The carb was tuned about as perfect as it was gonna get, fuel was good, the motor is in tip top shape.

He added about 30 drops of lucus in the oil and in 10 min the motor smothed out and to this dya still runs like a champ.

He recently rebuilt the motor so it would run on unleaded fuel, He expects the motor to be in the 400 to 450 hp range when hes done.

 

Lucas is crap. The reason it "fixes" leaking valve seals is because it makes your oil thicker, thus making it harder to seep around the seal. This also makes it harder for oil to properly lubricate your rotating assembly because it can't get into the close tollerances as easily. Imagine the difference between trying to squeeze water or honey out of a syrenge (sp). Same thing. The only fix for bad valve seals is new valve seals.

Stop-leak is crap. Not only will it plug a leak up (sometimes), but it will also collect on any kind of lip or rough surface. It builds up and makes your coolant passages smaller, and also acts as an insulator, which reduces your cooling systems effeciency.

The previous owner of one of my vehicles put stop-leak in and never told me. I saw rust in the coolant one day and did a flush, which took the stop-leak out. Next thing I know, the engine runs hot and I end up with an engine-less bronco II because the heads have cracked, pissing coolant into the oil which in turn whipes the brearings out. Complete rebuild.

If you have a car that you don't care about and just need to get it home, sure. Use it. Any other circumstances, the onlything you accomplish is making your wallet lighter.

I understand what your saying about how thick lucas is but I'm pretty sure once its mixed with regular oil its not as thick as your making it sound. Also every since I started using it my car doesn't blow as much blue smoke as it did with just regular oil and it burns oil at a slower rate.

 

Thats because the oil is too thick to get where it was getting before, which in turn makes it harder for it to get where its supposed to.

-Harry

 

So by your definition I should get the thinest weight oil I can find and then use that in my car?

Right.

 

If lucas made oil too thick and didn't allow certain parts to be lubricated im pretty sure they wouldn't be so well know and recommended so much.

 

Lucas is very thick....... howeever what it does do is BOND with the existing oil in the engine and it also sticks tot he mechanical parts. So where most oils fall through the motor tot he lowest point, the Lucas embedded oil stays higher up in the engine. So on cold start ups.... your valve train is well oiled. But on regular oils, your oil drops down tot he sump and remains there until the pump forces it to circulate through the oil passageways. This can over time lead to cam damage and bearing wear.
This is especially important to the people who are morons and fire up their car and just take off. Even on cold days. They do not allow the oil pressure to build up. Just start and hop on the freeway.

Lucas is good stuff. It is NOT a fake product. It 100% does what it says. Your oil will jump from say 5w30 to 10w30 value when used though.
It can both help and hinder your motor though. Thicker is harder for the pump to push....but an old pump might take a long time anyway to build up the needed pressure. so the Lucas helps in the dry starts.

Everyone should make thier own desision.
