Actual expense car/truck

[MGC94]

if you use actual expense do you put down gas for the whole year? 

Example $5,000 gas (even if it is business and personal gas and the miles will allocate the amount) 

Example car ins $200 x 12 $2,400 or do you only take like 10% of that if the schedule C is a small income amount? 

The 1099 is only for $1,800 as it is a start up business
