Ive narrowed it down to moble one for my 2002 V6 Tacoma after reading some great used oil analysis now i need to chose either SS or EP. I plan on sticking with 5W30 since im not buring any oil (55K) or will 10W30 give me better results? I plan on using either moble one or wix filters and change the oil and filter every 6 months between 5-7500 miles. Your info is needed thanks.
