Hey Yall,

Anyone else here use Lucas Oil Products? I currently use the Heavy Duty Oil Stabilizer on 3800 GM Engine w/180k miles mixed with 4qts Mobil 1 10W30. Although the 3800 is an excellent engine by itself i have noticed the Lucas Oil stabilizer to have quieted the lifters and lessen oil burning.

I did run the stuff mixed with Royal Purple in the same ratio on my 50k mile Camaro...BUT
on the Camaro it crashed my Fuel Economy 4mpg!!!!

According to Lucas Oil Tech Support they said my bearings/rings were in new and likely to close to factory tolerances which did not work to well with the heavy viscosity Lucas. Curious Point if anyone has experiance with this stuff.

I also use thier ATF Transmission Slip, Power Steering and Fuel Cleaner additives.

Mobil 1 and the 3800-II doesn't get along well I've found. I've been running the Valvoline products instead and my valves are silent. Many here don't like the valvoline products, for some reason, but I do and really enjoy the fact my 3.8L sounds like a camry 2.4L 4cyl at idle its so quiet [Big Grin]

Hmmm...at least i do not think i have seen any problems running Mobil-1 in our two 3800 Engines.

As faras the idle problem maybe next oil change I will try Valvoline synthetic and get back to you.

The idle does quiete down at operating temperature...have you at least noticed that? the 3800 is a buttery smooth engine none the less-

outrun rather than running a 10W30 and then pumping it up with an thickener-type additive, why not merely run a heavier oil?

Say ... a 10W40 or 15W40? [Confused]

I bet you'd get the same effect ... and it would be cheaper as well.

I have no experience with Lucas products except to mention that they have recently shown up on the counters of local AutoZone stores. Unless you have at least a tech data sheet, you are only guessing as to how you are modifying your oil.

That said Mobil 1 (as well as a few others) could use a bit of thickening. Don't get me wrong, M1 is a great oil. The Mobil 1 xW-30 oils are formulated to the low end of the 30 weight range...a fact that has kept me off of this oil. If you stay with M1, try the 0W-40. Amsoil 10W-30 ATM or Schaeffer's #703 10W-30 are formulated with a bit more viscosity in the 30wt range and would be excellent choices as well.

The Lucas is more slippery than regular oil and probably has better shear protection even though it fared the worse on Bob's bearing tests for wear. That's why I'd rather have run 10w30+Lucas rather than 20w50 or 10w40 alone. Those other additives that did better than it were designed to strengthen protection in different ways than Lucas. It's supposed to flow more with the oil rather than clinging to parts. Restore did really well on that test but its designed to cling to parts and not shear down. Thats why it helps old engines run better by using that clinging property to help smooth out worn cylinder wall surfaces.

I have used Lucas for the first time on my last Oil change and it reminds me very much of the STP Oil Treatment I used to use on my cars in the 70's.. [Smile] Just as thick and sticky.
I agree, if you lifters get quieter after adding this stuff then I would try a heavier oil in my car. 10W40 would be good to start. Or some have a 5W50 in case you are worried about the low temp viscosity

I'd go with Schaeffer's 132 if you need some slight viscosity increase.

Bright stock is good for gear oils, but engine oils?

Guys, Believe it or not Amsoil used to use 150 Bright stock in the older ARO 20w-50 racing oil. I don't know how much but it shocked me too.

I use Lucas UCL in both our vehicles. I premix it with U.S made FPC (Fuel Performance Catalyst) a fuel burn enhancer and add 200ml to tank before filling with Evo 98 fuel. It's pretty cheap here so must be almost free in the States.

What is bright stock and is STP Oil Treatment made out of the same thing?

From NORIA:Bright stock -- a heavy residual lubricant stock with low pour point, used in finished blends to provide good bearing film strength, prevent scuffing, and reduce oil consumption. Usually identified by its viscosity, SUS at 210F or cSt at 100C.

The base for STP is polyisobutylene, an olefin copolymer. It increases oil viscosity much the same as bright stock, except it leaves very little residue as compared to brightstock.
