When my car gets temperamental using Baja Sur Magna, which is the same as mainland Magna. OR (and this is a biggie) when several thousand miles of
garbage USA gasolines, this is what happens. Start-ups are not smooth. The engine rocks badly and stalls. Put it in gear and it hesitates or stalls
right off. Fuel mileage over a given course USED HUNDREDS OF TIMES degrades about fifteen to twenty seven percent. On another trip to Acapulco the car
got 18-miles per gallon. I didn't know about Premium then. So I went to COSTCO Acapulco and purchased 4 cartons of six bottles each of TECHRON. I
filled up leaving the city after adding Techron. Thereafter the mileage resumed to 27 mpg for TENS OF THOUSANDS OF MILES. The same thing happens with
junk USA gasoline so I stick to Chevron and so not use Techron additive.
SORRY CHARLIE, I put too many miles on that car to get fooled by such things as more or less traffic, different routes, different levels of wind, the
possibility of getting "bad" tanks of gasoline. When the engine STALLS, 101% of the time using off brand fuel, when the mileage dumps, it is not
subtle. It is rude. With gasoline using the urea additive (Chevron Techron, Shell's Nitrogen additive) the stalling, hesitation and crappy fuel
mileage does not appear, EVER. orget about temperature differences, most of the miles except in the states occurred between 55 and 120 degrees. The
car runs even WORSE when it's hot.
Calif emissions test last year. ALL TEST RESULTS were way, way under the maximum. The car has 80,000 miles. I purchased it when it had sixteen
thousand miles.
Apparently MOST other engines are not as sensitive as the Mitsubishi. But some are. On a trip to Mulege last month I averaged 28.8 MPG. FILLED FROM 19
liter gas cans to ensure accuracy. |
Gas here in Denver jumped over 30 cents in the last week or so
