I add some Sea Foam Motor Treatment to my carís gas tank twice a
year with the hope that it will take care of any water that has
accumulated in the gas tank due to condensation. Is water in the gas
tank an issue most people should worry about? Is Sea Foam doing what
I hope itís doing? Am I just wasting my money?
ó Phil M.,
A: You didnít
mention the year your car was manufactured. Vehicles built in the
past 20 years have fuel systems that are well-sealed against
evaporative loss, which should minimize moisture intrusion. Iím
thinking the most likely way water would enter the tank would be
through contaminated fuel.
claims to keep the fuel system, part of the intake system and
combustion chambers clean. It also keeps fuel fresh and is purported
to help with moisture contamination. Iím not privy to information
that proves any of this, but the product does have a significant
following of folks who think itís useful.
using an E-10 (10 percent ethanol) top-tier fuel, youíre already
doing pretty well on cleanliness efforts, and the ethanol absorbs
moisture, bringing it through the system. My í97 Chevy Tahoe has
arguably the worst fuel injection system ever, and I toggle back and
forth between Sea Foam and Techron every couple of months to keep
the engine running smoothly. Even when I lapse and the engine
becomes missy, adding either product brings back smoothness within a
week or so. Ed, my fuels guru, says a bottle of quality cleaner
provides about 10 times the cleaning agents of a tank of top-tier
Q: I have a
1990 standard transmission Toyota Celica All Track Turbo with just
over 120,000 miles. It has not been driven for six years. What do I
have to do to drive it again?
A: Cool car!
Your largest concerns will be the battery, fuel system, brake
system, cooling system and tires.
battery. Fuel remaining in the tank and injection system will be
stale and nasty. It would be best to siphon out as much as possible,
refill the tank with fresh fuel with an additive such as those
mentioned in the answer above, then change the fuel filter after a
few hours of running and again in a month or so. Your brake rotors
will be rusty, and hopefully the parking brake wasnít applied all
this time, as it could be bound up. Cleaning up the rotors would
lessen the chance of fouling the brake pads, and a flush and refill
of brake fluid is needed. Sticky or leaking brake calipers are
possible, but not likely. Drive it and fix them as needed.
and hoses and draining and refilling the cooling system is a good
idea. Hoses deteriorate from the inside, making inspection
difficult, and you want to avoid a corrosion issues with the
coolant. Itís not a bad idea to also renew the spark plugs. They
didnít deteriorate from sitting, but the retaining threads are
ready for some exercise. Check the tire identification number on
each tireís sidewall (look for "DOT" followed by a
string of letters and numbers). The final four numbers are the week
and year the tire was manufactured (0310 would be the third week of
2010). If theyíre approaching 10 years, consider replacing them,
regardless of tread remaining.
