Lucas Oil in the Winter? Check the time it takes for the low oil pressure light to go out. That
should tell you if you've got a problem.
Lucas recommends 20 per cent concentration, for my 2.2 liter that works
out to 3 cups out of a quart bottle.
Lucas coats the surfaces and does not drain off overnight or even
longer.
I liked it because it avoided the slight seepage around valve guide
seals.
BTW, Valvoline Maxlife synthetic may be a synthetic blend rather than a
fully synthetic oil with a PAO (polyalphaolefin) base. Legally, if the
oil is modified it can be called synthetic without necessarily
providing benefits of a fully synthetic oil like Mobil 1. Also, the
"Maxlife" may have seal "conditioners" for higher mileage vehicles
which can cause the seals to swell. Personally I never liked that idea,
because if you ever stopped using that type of additive, seals could
potentially leak even more. This is one of the things I liked about
Lucas, there are no solvents or particulate additives like Teflon.
I was surprised to hear Click and Clack the Tappet Brothers debunking
myths on the radio a few weeks ago. A lady said her husband believed 80
per cent of engine wear occurs on a cold start, and they said that is
correct. That the first few seconds, generally 3 to 5 seconds, or
perhaps the first 20 to 30 seconds at below freezing temperatures, it
takes for oil to begin to circulate to the areas furthest from the oil
pump, there is metal to metal contact.
Then I looked again at the Lucas oil bottle claiming "prevents dry
starts, the number one cause of wear in new engines" with a little less
skepticism.
I would recommend you use the correct concentration unless you've got
extraordinary engine wear conditions. The Lucas should completely mix
with the engine oil so the viscosity when hot is altered only very
slightly. If you notice a problem with the oil light staying on longer
then you may have an issue, but otherwise, you are probably better off.
One of the comments I liked in doing research before trying the Lucas
products, was the people commented the oil clinged to the dipstick even
after sitting over night.
If you want to ask Lucas directly, their phone numbers used to be:
800-342-2512 and 909-270-0154.
My car stays in the garage, and temperatures are rarely below 60.
Actually, Mobil 1 also, by inference, seems to recognize the concern
about cold start up. Their solution is that since the synthetic oils
flow better at low temperatures, they reach critical areas sooner. So
that would shorten the time but not eliminate the problem.
If your Maxlife is not full synthetic, the cold flow properties may
also be sub optimal. |
