l have a 99 dodge intrpid with 130,000 miles, alot of people have been telling me that the engines on this model tend to give out rather early. what can l do to prevent this from happening to my car?

Well, with 130,000 miles I'd say you have already proved them wrong. Use Lucas Heavy Duty Oil Stabilizer with every oil change. Keep air filter clean.

owned a 98 intrepid had a 2.7 motor,took very good care of it.ran rotella t oil and added lucas motor additive. it got sold at 155000 miles and it was still going strong.

2.7L engines have issues with sludge build-up, causing oil starvation & engine failure. Most would agree that regular oil change intervals, with a fully synthetic oil is recommended for long service life. The powertrain has a rather weak cooling system design, causing above normal engine temperatures to break down conventional oil quickly.

Look at online forums for results of poor maint. practices & many unhappy customers.
Properly maintained they last as long as most other like vehicles.
