My friend bought an 07 STi with 70k miles two months ago. I checked his oil today and the dipstick was dry. I told him to fill up from the 10 quarts of Valvoline Ultra 10w30 he has in his room, before starting the car again. He insisted on buying 5w30, since it is recommended. Whatever. Anyway, the car took 3.5 quarts. Would it be a good idea to do a used oil analysis? Anything else to check. I convinced him to go with Rotella T6 5w40 on his next fill.
He says the extended warranty will cover a new engine.
