I was wounder which was better Rislone or Lucas. I was changing my oil and a buddy of mine came over and seen me putting rislone in, he said lucas is way better. Whats the truth.

 

IMO, they are both snake oil...but then again, that's my opinion.

 

Rislone, I would not put in the "snake oil" category, as I would with other oil additives, some still on the market, some that went "belly up". Rislone has a good additive package, but it's primary use is cleaning up neglected engines, with sludge, varnish, and other deposits. If you have an engine that has had it's regular oil change schedule (with new oil filters) Rislone is not necessary. I feel Rislone is a much better choice than adding a straight "engine flush" which is basically 80% kerosene and 19% kerosene by products. 1% "Mystery Chemical", known only to one person in The Pentagon, Washington D.C. Those water thin flushes can cause more harm than good, by dissolving and clogging oil pumps and block passages from sludge. Rislone is a better lubricant. Rislone is great in small engine products (edgers, lawnmowers, 4-cycle powerplants). Add about 10% Rislone to the oil capacity in those small engines. I don't know enough about Lucas Oil's additive to comment honestly. If you are talking about the Lucas Oil Stablizer product (?) I would only use it in a worn, piston slapping, beater engine, where you have noticeable blue oil smoke haze coming out of the tailpipe. (Some of those old, worn motors end up lasting another 100K!) If that is the Lucas Oil product you are speaking of, and your engine is tight, running normal, then I feel the Oil Stablizer is not needed, despite how the little nylon plastic gear demonstater works at the auto parts store. Just my opinion. Anyone else? Am I missing something? Thanks, ED

 

The best thing for your engine is... -drumroll-

OIL!

Now you know. You heard it here first. The oil companies put millions of dollars into developing an engine oil that will provide excellent protection of your engine. Use oil with the right API ratings, and you cant go wrong.

If you think you need an additive because your engine makes noise, smokes, or other problem, then you should use the next higher viscosity. For example, instead of using 10w30, change to 15w40. Far more effective than any additive.

If that doesn't fix it, a rebuild will.

Oil additives = throwing your money away, IMO.

 

Rislone in analysis will look something like this:

Zinc 380
Phos 350
Calcium 760
TBN 5.0
Vis@100C- 9.2

It is a basically a 20w oil with very few additives. There is more value in a bottle of Walmarts El Cheapo 5w-20 than in this stuff.

Lucas is made from bright stock. Bright stock is a heavy residual low cost lubricating stock. It provides good bearing film strength, prevents scuffing, and generally reduces oil consumption. But there is a problem here. All testing I have seen on it has it foaming at temp. It apparently lacks anti-foaming agents in sufficient quantities to handle the extremes.

My suggestion, keep your money in your pocket.

 

If you want to add something, Valvoline Synpower Oil Treatment is very good or add 1/2 quart Redline Motor Oil.

 

A co-worker who ran a trucking business for over 30 years offered me some advice when my 94 Crown Vic with 135,000 miles started burning oil. He suggested I add a quart of Lucas to my next oil change and he guaranteed the oil burning would go away. I've always trusted him, so I gave it a shot. Did my usual Valvoline MaxLife 10W-30 with a quart of the Lucas. That was a year ago. No more oil burning or consumption. Oil level is always at the full mark. Could be coincidence, but I'm sold on it. Since then, I've done (3) oil changes with the same results.

 

That makes sense. Lucas thickens the oil. You could get the same results by switching to 15w40, and it'd probably cost less.

 

Good point. Never thought of it that way. I may try the 15W-40 next time and see how it goes. $8.99 a quart for the Lucas does add up every 3000 miles.

 

The Lucas is very sticky and will help in cold starts. I've used it since i got my Bronco a few years and 70,000 miles ago. I now have 270,000 on my 302, and it does not burn oil or knock. The only problem is the rear main leak which was leaking since i got it, yet it has not gotten worse. If I had not run the Lucas I would already be on my second engine. This is worth the $24 for a gal, or $6 / qt

 

I should clarify what I didn't mention earlier, I think that Lucas has some merits, just not in an internal combustion engine.

No offense meant, but Lucas WILL NOT make cold starts easier! Lucas is not a multiviscosity oil, it is a heavy 60 or 70 straight weight at best.

I have a gallon of lucas that only gets used in old gear boxes on the farm, and I assure you that 80w90 pours faster at 10F than Lucas does. In fact, you have to spoon it out or squeeze really hard on the bottle.

As said before, a multiviscosity oil is much better, 10w40, 5w50, 5w40 are some that come to mind for good cold starts and leak resistance.

 

Sorry, I meant to say helps eliminate dry start ups, not cold. It is very thick, I often place a quart of it on top of my furnace in the winter to thin it out for a half hour before i have to pour it in! It will not help crank over the engine, but will help reduce friction caused by the dry startups, after the engine has been sitting. Thank you for correcting me.

 

I know alot of people bash Rislone as snake oil but for me its worked. Had a buddy that had a 96 Firebird with 40k no oil change since the factory. I dumped 2 quarts of Rislone and 2 quarts of oil drove it around for a few days and was actually able to get something out of the plug. Added a quart after a few times ran better after a while. But he only drove it for another 20k till the tranny went out. I've added to my truck and comsumption drop some and oil was extremely dirty. Although don't run it straight smoked a lawn mower good doing that, thankfully I had Mobil1 in it also. I think for a good running engine nothing but a good HDEO treatment ever 10k is necessary. I've used Lucas in a Aspire that had alot of blow-by. It's nothing but heavy oil with alot detergents , but get really really thin when warm like water. Like I said I wouldn't run either in a good engine.

 

I would run 1/2 quart to 1 quart Lucas in a new engine along with the manufacture's recomended very thin oil. I wouldn't go over 15%-20% Lucas in it.

 

Still think lucas is a good thing for your motor?

This is enough proof for me not the use it in my motors....http://www.bobistheoilguy.com/images/lucas/lucas.htm
