Default Engine Cleaning Additives - What is good and what is not?

Hi,

I have a 2002 Camry LE V6 with about 60,000 miles on it and change my oil
every 4,000 to 4,500 miles with Mobil 1 5W30 oil (85% highway driving 100
miles a day). I have heard and read about these additives that one can add
to their oil and it cleans the engine out. I was wondering if someone has
tried this and if it makes any difference. My concern is that if any crap
gets loose with these detergents, it could possibly block parts of the
engine and restrict oil flow in those areas and cause more harm then good.
Is that possible or am I wrong.

Based on the above, you have absolutely NO reason to be concerned about
varnish, sludge, or the Charlene scum around your tub!

I tired one of the oil cleaning products. I change the oil around 3k on
my '93 Pickup and even at 270k miles at the time, it still came out quite
clean. So I figured what could it hurt. I dumped some cleaning stuff in
and did what the lable told me too.

What came out of the pan when I pulled the plug shocked me. A thick
brown, mud like liquid. Grit, dirt, everything. I was and still am
worried that all that crap blocked something in the engine. I changed the oil a few
times after that to help flush it out.

The truck is now at 302k without any problems, but I do not want to try
that flush again. I figure any dirt still in that engine has not caused a
problem so far, so it's staying.

They are a useless and potentially dangerous thing to use IMO. They in
theory, loosen any deposits allowing them to go into the sump to be pumped
into the oil-filter until it blocks and bypasses the grit to the
bearings,.....not a good thing,...but I dont think they work anyway.

I would not worry about it. I have a 97 4 cyl using Pennzoil changed
at 3-4000 mile intervals and theres no gunk under my valve cover...
BTW I have 190,000 miles on it now. Since your using sythentic
oil I would think yours should be as clean as possible anyway.

Doing a lot of reading/research online, I've seen people swear up on down
about Redline and BG44. Those seem to be the most popular ones for Toyotas
(or at least Camry's). So I picked up a bottle of Redline and gave it a go.
I've got
a 1994 Camry with 160K miles. That was about a week ago and I'm pretty sure
I've noticed some increase in pickup. Haven't tried BG44 yet, you can only
buy it
online.. at least no place around here sells it.
Curiously, I was at my Toyota dealer today inquiring about various
maintenance
services and one that they have is called "BG Carbon Cleaning Service" for
$169.95.
Its the same BG that makes the BG44 fuel additive. I know that the carbon
cleaning
service has nothing at all to do with fuel additives but at least Toyota
trusts BG
enough to use on their cars.

BTW, has anyone ever heard of or had any experience with Fuelon? Its reddish
and
comes in one of those clear containers where you measure only a bit at a
time to add
to each tankful. Supposedly it improves fuel combustion and clears out
carbon from the
engine. And supposedly it'll make any vehicle pass emissions testing (I
guess by reducing
NOX?.. a result of hotter combustion?). I'm a big skeptic so I like to hear
other peoples input.

It is not Toyota that trusts BG, it is the dealer you were at.

An oil viscosity enhancer can lead to varnish formation and cracked rings.
One reason why wide viscosity oils were not recommended by the car companies
after that finding came out. Why not just switch to a heavier oil? 10W-30
instead of 5W-30 for example.

Richard.

The only one I used was BG RF7, an oil viscosity enhancer for my end
of life Corolla with an oil light that flickers at idle.

It worked for about a year - not bad IMHO.
