I bought my 99 corolla w/ 111,000 miles. I have a co-worker who has a 2000 corolla and he has over 300,000 miles on it. he recommended the following and I want to know what you guys think:
1) buy a quart of marvel mystery oil at Kragen and pour it into the engine and run it for 500 miles. supposedly, it will clean the engine up. Then change oil with the following:
2)
get the Tough guard Fram and add 3 quarts of 20-50 synethic and 1 quart of slick 50. He said to change the oil every 5 to 6 thousand miles.
he recommended the better filter because pump doesn't have to work as hard and there's better flow AND filtration. What kind of filters do you guys recommend? OEM or is the tough guard better / worst?
3)
I'm not too sure about the 20-50 synethic.. i'm thinking about giving my 111,000 miles car 5-30.
4)
Does pouring in different weight oil affect the timing chain? The reason I ask is because I hear the oil is used to presure the timing chain / guide. ..so in theory, the wrong weight plus the wrong type of filter may affect the timing chain pressure---so won't this cause quick wear and tear to the timing chain?
he says he typically gets 400+ miles on a full tank on his corolla 2000.
5) will the slick 50 cause harm to the engine where it the teflon coats certain parts of the engine ..etc..
Thanks,
Gordon
