These are a performance engine and should be driven differently than a lot of other vehicles. Numbers 1 - 3 apply only to manual transmission cars.
1. Never operate the engine under 2000 rpm in any gear except fifth (see #2) (except when you’re under 20 mph in first).
2. Never operate the engine under 2500 rpm in fifth gear.
3. Never shift before 3000 rpm.
4. The power band in a stock L engine is between 3000 and 5500 rpm. If you’re below 3000rpm, down-shift into a lower gear for more power.
5. It does NOT hurt to take the engine up to 5500 rpm before shifting.
6. It does NOT hurt your engine to run between 3500 and 4500 on a continual basis as long as your engine or oil temp doesn’t climb above normal.
7. If you do a lot of stop and go driving, or don’t drive your engine very hard, then we recommend a poor mans tune up every 500 miles minimum (see #15).
8. These engines should never be operated at 190 degrees or above. If your engine starts to run too hot or overheat, SHUT IT DOWN IMEDIATELY, because it can cause extensive engine damage.
9. In the summertime you can always get additional engine cooling by turning your heater on high.
10. Always change your anti-freeze every 2 years, or at least have the Ph level checked and/ or set as needed.
