I purchased a new 08 Mitsu Lancer Evolution in April. 1st 500 miles used the 5w30 M1 from the Factory, now I changed to M1 EP 5w30 every 4500 miles. Car has 9550 on the ODO. I am sending the the M1 EP 5w30 to Blackstone Labs for a oil analysis tomorrow.
I have a feeling that the results will be grim though, I am not sure if M1 is up to the task of handling this turboed motor very well. The 4B11 TURBO has been associated with having a fuel dilution issue (not all the motors just some), which causes the oil to lose its viscosity.
As well as the the cars oil does heat up quiet a bit, since the turbo is located in the rear of the motor (car comes equipped with a oil cooler with thermostat).
I have modified the car with some power adding parts. Which include: -CBRD Tune -COBB AP -COBB UICP, LICP, BOV HP -COBB SFI -COBB Turbo Inlet Pipe -COBB Sway Bars -ETS 4" FMIC -AMS DP -T1R Exhaust -MXP TP -FORGE WGA -xMR Catch Cans -AMS Front Rollerstop -AMS Fuel Rail -evoDynamics 3 Port -Deatschwerks 800cc -Techna-Fit SS Lines -TWM Short Shifter -WORKS Bushings -SWIFT Sport-Mach's -Whiteline Kit -AEM UEGO -STRI PSI Gauge -Rally Armor Mudflaps -PERRIN 3" Ant.
With all these parts (not all for engine performance) the car turns out about 360whp and about 26-27 PSI of boost.
I run the car through 2-3 AutoX session a year and spirited driving. Includes some jack rabbit starts, and some passes through gears through the RPM range. Most miles are about 65% highway, 33% city, and 2% racing.
This is my daily driven car, so I need it to run in tip top shape. Highway in 5th gear is 80mph at 3800rpm. So the oil does take a bit of beating.
Now the question is: (after the M1 Results Come back in)
Switch to something like Redline 0w30 or 0w-40 or give AMSoil or GC a try.
Some input would be required, because it is a high performance close tolerance engine.
Factory Spec 5w30 Full Synthetic (M1 recommend advertising on the motor) change interval 3000-3750.
