SHESH,
800 KM in Maruti 800 is doable. Important points to keep in mind.
1. ESSENTIAL CHECKS, BEFORE COMMENCING JOURNEY.
a. RADIATOR COOLENT. Change this, unless it has been changed recently. Carry an additional 1-litre distilled water, in case a top up is required enroute.
b. ENGINE OIL. Check and change, if required.
c. TYRES AND TUBES. Check all 5 tyres (including Stepney) for correct pressures. Tyre and tube changing equipment is a MUST carry in the car.
d. HEAD LIGHTS. Very Important if travelling at night. Ensure that the lighting is GOOD in both low and high beams. Keep a spare pair, if required (PHILIPS is a good brand).
e. REAR LAMPS & INDICATORS. Should be in perfect condition.
2. CHECKS DURING THE JOURNEY.
a. ENGINE TEMPERATURE. Keep an eye on the guage. This should be preferably below the 50% mark. Please stop for some time, if over-heating is noticed. Switch off the engine and allow it to cool down.
b. FOG FORMATION & CLEANING. Common problem in night driving. Use the Heater to blow off the Fog. If there is no Heater, please wipe off manually. DO NOT DRIVE WITH FOG ON THE WINDSHILD. IT IS VERY DANGEROUS.
3. ADD ONS DURING THE JOURNEY.
a. Carry a blanket / wear thick clothing (if overnight driving) - keeps you and your co-passengers warm.
b. Carry good amount of drinking water. Avoid eating HEAVY food at road side DHABAS on the Highway.
c. MOST IMPORTANT. DO NOT FALL ASLEEP ON THE STEERING.
YOU ARE DRIVING SUCH A LONG DISTANCE FOR THE FIRST TIME. PLEASE REMEMBER - HIGHWAY DRIVING IS NOT JUST SPEEDING. IT IS AN ART. AND YOU NEED TO LEARN IT.
HAVE A SAFE AND ADVENTUROUS JOURNEY.
Regards.
Narasimham.
