My owner's manual says to use synthetic blend 5W-20. Do I HAVE to or can I get by with conventional oil? Yes ideally, I'd like to go full synthetic but $50+ for a full synthetic oil change? Damn!

A while back advance had 5 qts of Mobil-1 & a Mobil-1 filter for 29.99..

But Motorcraft Syn-blend 5w-20 and a MC filter shouldn't be close to $50..

Used to spend about 30 but now its about 55 per change , I use full synthetic . Newer truck , 2010 . My old ranger ( 2000 ) I put synthetic in too after about 50 K . Best thing I ever did .

Yes you're fine with normal dino oil still. I don't think synthetic even existed in 1997 so I don't know how your owners manual can even suggest it. None the less, you can use regular oil without a problem.

I use Valvoline full synthetic for high mileage engines, 5w30.

i have castrol synthetic 10w/30 and one quart of castrol 5w/30 to thicken it some so my rockers and lifters got an extra coat of thicker oil instead of useing additives like lucas i was pleased that my 23 year old engine could still run castrol that shizz is like sewing machine oil,thin,clean,and clear as water,took 6 months to turn it to a regular brown color like ford motorcraft,at least my ol'2.9l runs as good as a new 2010 mustang with castrol,and i know my engines clean and tight,and like new running shape dispite it's age,HA just like the castrol mustang tv commercials,now it's back to motorcraft 10w/40 for winter.

LOL, my Ranger is a 2003, my Taurus is the one that's a 1997, which by the way, I use high mileage oil. Like it says in my sig, both have the OHV 3.0L V6.

I use 5w-30 for winter, and 10w-30 for summer. The reasoning: in winter, you want a lower weight of oil so it doesn't gum up, or get thick for your engine. Then I switch to 10w-30 during the summer because heavier oil stands up against heat better.

The brand I use is Castrol GTX high mileage. Never had a problem with them.

5w30(recommended by ford) Mobil 1 full synthetic(it makes my engine happy, I can tell)
