Toyota

I have an 02 sequoia sr5...now, i know all about the cold weather ticking the engine makes and low oil pressure readings....my question is, can anything be done about it...hearing that awful knocking sound when its 30 degrees outside makes me dread starting the thing. i am already using synth oil 5w 30...can something like slick 50 help?

All of the above junk is great info if it mattered or you had 150 k miles on it, you can try a factory oil filter from toyota they have a valve in them to help oil drainback while setting
