octane requirements. Use of regular grade gasolines in higher
performance engines may result in potentially dangerous engine

CHEVROLET OWNER PROTECTION PLAN
The Chevrolet Motor Division considers it a most im­portant obligation to offer each owner a recom­mended maintenance service guide which will relieve him of any anxiety and insure that his vehicle is regularly inspected and maintained.
Your Chevrolet dealer has presented you with a Chevrolet Owner Protection Plan Booklet. The rec­ommended Maintenance and Lubrication Service items in this Plan Booklet have been worked out by Chevrolet service personnel and cover items which are
the owner's responsibility to have checked, inspected, adjusted and lubricated at recommended time or mileage intervals.
If the services afe carried out at the prescribed time or mileage intervals, wear and owner expense will be kept to a minimum. Additional services may become necessary as mileage accrues; however, the regular visit that you make to your Chevrolet dealer in fol­lowing this Plan will point out desirable services as
they become necessary.
