Compare power alternatives for oper- ating cost — performance. Not tradition ... not old standards.

Cat 3500 Series offer unequalled efficiency with no sacrifice in performance. Compare ...

Fuel efficiency. Fuel represents up to 90% of an engine's owning and operating cost. So it's easy to understand why the Cat fuel efficiency advantage can save you so much.

Performance. Ask someone who has operated both makes. The Cat 3500s with higher cylinder displacement handle the load better and have added punch for superior response.

Maintenance Ease. Direct accessibility to crit- ical engine components and maintenance points on

Cat Engines makes inspection and adjustment easy.

Fuel and oil filters and lube oil are changed at the same time. On the 3512 and 3516 this maintenance is required only once every 1,000 hours.

Price. It may be a surprise ... the 3500s are very price competitive, even before you total up lifetime owning and operating savings.

Overhaul expense. Cat 3508 and 3512 Engines compete in the same performance class as Detroit

Diesel models operating with four more cylinders each. So when you overhaul, you'll have fewer parts to replace, lower labor costs.

The way they're built. The 3500 Series are heavier than Detroit Diesel 149 Series engines ... but the extra weight is in critical areas — Between cylinders, in the crankshaft — where lighter con- struction can lead to shorter life and more parts replacement.

Have your Caterpillar Dealer help you make a comparison. He'll start by running a fuel analysis comparing Cat to Detroit Diesel or any other make engines. Then have him provide you an in-depth investment analysis so you know what it costs to own and operate a Caterpillar Engine over its long lifetime.

Consider your alternatives . . . your decision will be Cat 3500 Series.
