I agree with roadrunner, there is actually a specific "break in" oil, which I used in my bike after a rebuild, A new motor may need the extra roughness that conventional oil, or worse oil, can give. I know harley for a long time said bearings would not spin, ect due to the extra slipperiness of synthetic oil. Now they have synthetic oil, go figure! Everything does need to be properly set though, and could benefit from the conventional oil. I am a big fan of synthetics, and as far as the old car and more leakage, thats only true when the oil is cold or cool. As conventioanl oil is heated up it becomes much less dense/viscose, and thus the lack of protection, and will leak more than a synthetic oil. So go ahead and use synthetic in all motors, no matter what the condition. It stays at the set viscosity, and if leakage is of conserne, use a thicker synthetic. PEACE

 

Mopar222 is right as well as 71RoadRunner. The engines today are much "tighter" and don't need the lengthy break-in periods our parent's cars did. Ditto for the oil. Synthetics are gaining a larger peprcentage of the market each year for one major reason - they work better and protect better than conventional oils. Some old "die-hards" refuse to accept this and still tout regular dino oil as the way to go. They're the same types that have hung on to typewriters and 33 1/3 rpm records....

 

I put in a pressure pipe and HKS and the frist time drive it was getting 15, 16 pounds of boost, i didn't drive it for a week and now its not quite getting 15. just got the srt-4 dont konw much about after market parts? george (depressed)

 

Check your install for leaks. Also, your max boost will depend on the weather (temp) as well....

 

Yep. I have been down on boost for awhile(12 psi max and steady) due to the rain and humidity, although I was beginning to wonder.[sm=smiley24.gif]But I jumped into it today since it is nice, sunny and dry and it got up to 15 psi max with a steady 14 psi, so now I fell a little better.[sm=smiley16.gif][sm=smiley2.gif]

 

so if it comes with synthetic from the factory, it's cool to just keep using synthetic right??

 

Yup, the engine is made for it, needs it, and DCX recommends it. [&:]
