Default Lucus oil-To add or not to add?

Any one use this stuff before? Does it live up to all the hype lucusoil.com
pumps into it? Do you have to go with a lighter oil grade, say 5w30
instead of 10w30 if you do decide to use it?

any insight is appreciated.

I really can't tell you much: some people swear by it and say it works
great, but then I saw a Web site that did a test and proved it foams,
which is NOT a good thing! (Yeah, EVERTHING on the Internet is true; not
like perhaps the people who did the test had a bone to pick with Lucas...???)

WHY do you want to add an additive? High miles? Looking for added
prevention?

Here's what I have been doing for 30 years, and STILL have one of the
three High-Mileage cars in my driveway to prove it:

I add 1/2 quart of Marvel Mystery Oil to the 3 1/2 quarts of Castrol GTX I
put in every 3,000 miles. Three cars well over 220,000 miles...

A good quality synthetic oil is, IMHO, better than the best additive added
to dino oil.

~~~~~~~~~~~~
I use Mobil 1 10W30 full synthetic with Lucas 20% concentration in a
5S-FE, (4 cylinder) 1994 Camry with 130,000 miles.
Also use their transmission product at 15% concentration in the
automatic transmission, combined with Mobil 1 fully synthetic ATF -
same in power steering, and a very small amount 5% concentration in the
differential.
~~~~~~~~~~~
I also ran Auto-rx (auto-rx.com) in the crankcase one time for 500
miles and then drained.
When I purchased the car with 84,000 miles, running conventional oil, I
also changed more frequently a number of times, experimenting.
I also changed the seal on the engine and transmission oil pans and
cleaned the interior - although both were already fairly clean.
~~~~~~~~~~~
Lucas in the engine stopped the puff of smoke from the valve seals on
cold start.
In the transmission, quieted operation - and I like the extra
protection for the planetary gears. I have never observed any evidence
of foaming anywhere when checking oil levels or draining with engine
hot.
In the power steering, response at slow speed was improved.
In the differential, I noticed an improvement in power with Mobil 1,
but a decrease when adding Lucas there, so I scaled back the
concentration.
~~~~~~~~~~~
In addition to no smoke on cold start, the engine uses a very slight
amount of oil and leaks none - although I have changed all the oil
seals and gaskets - it is the rear main seal I'm looking to preserve.
~~~~~~~~~~~
I do not use Lucas fuel treatment, because it references running
hotter.
I use RedLine complete fuel system cleaner which is safe for continuous
use, and also keeps the valve faces clean.

I need to get better oil coverage to the top of the motor. I figure if
lucus coats as well as they say it does, then its something I should try.


I also want to eliminate some of the burning. I heard that Lucus is great
at reducing heat friction-less wear=less burning. My 91 4cyl camry has
155k miles on it so I realize that some oil consumption is innevitible.

On the same end I am affraid to stray away from my simple 4 qts of maxlife
10w30. I change the oild every 2k to minimize the slugging that takes
place.

Is there a problem with oil coverage to the top of the motor? Why?
Your running maxlife 10w30 in the summer in a 15 year old
high mileage motor? I would go to 10w40 high mileage oil..2K is really
too soon to change. I go 3000 or more between changes on a daily driven
97 with 200,000 miles. No oil leaks, uses about
1/2 qt between changes.

I thought thinner oil was supposed to travel more easily to the top then
heavier oil?

Well thinner oil will pass by the oil seals and rings causing MORE
burning. Again WHY do you think you need MORE lubrication to the top of
the motor?

I hear a slight but distiguishing tick coming from the motor. I have been
told that this is normal for this motor(2.0) but I cant Help but think its
a lifter. I know going heavier just makes the engine work hard to
circulate the oil so I'd rather go light with a product like lucus that
will stick to the motor and mix with the oil instead of 10w40 which will
just drain back into the pan and sit. Plus I know that going heavier will
mean sacrafising gas MPG and we pay 2.50/gal around these parts.

The Camry uses a bucket and shim arrangement for its valves. I think
the adjustment interval in the manual is 60,000 miles.You probably need
yours adjusted. You think Lucas oil additive is lighter? Its like
molasses. Its todays equivalent of that STP additive from the 1960s.
People used it to dump in the motor to quiet them down and stop ring
smoking just before they sell them! Fix the problem dont just treat the
symptom. Your not hearing the ticking of the fuel injectors going off
are you? The older ones were noisier. Whats the condition of the top
end of the motor? Have you taken off the valve cover and looked for any
sludge buildup?
