I've just purchased an 04 Liberty 2.5i manual and wonder if anyone has any tips as to the best way to 'run in' this engine? I've also heard that although not specified the engine does respond better to running on a premium level fuel. Does anyone know if this is true or not?
I'm sure you will get many opinions on this but, the following has worked for me for Volvos,Saabs and Subaru's which were sold at mileages of greater than 150,000 miles and running very good. . I frequently check oil and fluid levels in addition to leak inspections during the run-in period. This is my plan. I always let the engine idle for one full minute before driving off and then I drive easy until the temp gage if fully warmed which is about
7-10 minutes depending on the outside temp. I try to drive in a suburban setting; that being some stop and go with periods of cruising at 40-60 mph. I use light to medium throttle. After 300-500 miles of this I increase the shift points from ~ 2500 to 3000 AFTER the engine is warmed up. From 500 to 1000 miles I drive normally but, using more throttle; say up to 3500 rpm. I continue this general procedure until the first oil/filter change or ~2500 miles and then do as your heart desires. Some where ~ 1000 miles I like to see the engine red line in all the gears. One other comment; If you drive a manual DO NOT lug the engine and with any vehicle do not drive for long periods at one speed i.e. cruse control. Happy driving. eddie
Regarding premium or normal ULP, Subaru Aust have their own recommendations on their website :
I couldn't have said it better.
About the premium fuel, the mid octane works just great for me.
What does "lugging" the engine mean? Is that the same as engine braking?

Using too high a gear for the road conditions. For example, trying to climb a steep hill in 5th gear with the engine labouring below 2,000rpm.
