my boss doesnt know which end of a hammer to hold but he knows better then to question what his car needs when it breaks. But the other day he went to the local castrol place and the head guy there told him to get 10w30 instead of 5w30. he was kinda puzzled but when the guy said (its Africa hot here, you know that) he agreed and got the 10w30....
last year the coldest day was 30 degrees, and i think it was the only day under 40 degrees. its over 100* normally and peaks at ~117* or more.
do i ( in general) need to worry about cold start ups? i usually let the trucks idle for about 30 seconds befpre dropping them into gear.
on another note, is 10w30 stronger (other then being a 10 wt and different flow rate) then 5w30?
i have 3/4 things in my head that are conflicting, like the specs some owners manuals ive seen in the past for cold starts and or oil weights being much stronger today
