The 20/50 weight oil does not have the "cold pumping properties" that the 10/30 does. The engine needs that lower # at start up to get good circulation throughout the oil gallery. Also, the heavier oil on the upper # will hurt your gas mileage and power considerably (you can feel the difference).
Thank you both!
I changed the oil like that MIJ said. Thank you SnookWhaler for the explanation! that's the better way to learn about our cars, here at the forum! I paid $12.65 for the oil filter (at the dealer)but it's better than a cheap filter in long terms and I almost paid $65 for the oild change (Castrol semi synthetic oil). A qt. of synthetic oil costs $22.52 and semi-synthetic $12.43
I'm planning to change the spark plugs tomorrow but i couldn't find the GAP of .28, i could only find .8mm that would be as 0.29?? Could this be a problem? the brand name of the spark plug is VERON.
An additional question, It is the first time that I change the oil, and I just wondering if the previous owner used a cheap brand of oil, and now i change it with a better brand and weight that could increase the pressure of the engine?? I ask this because when I revise the fire trap it it was obstructed, so I clean it up the best I could, but is it better to change it once and for all?
