oil change question
I have a question for you. I have a boat with a 302 engine in it. The only way to change the oil in it is to suction it out through the dipstick tube. I am thinking if I buy the suction device does anyone see a problem with using it on my F150 4.6 to remove the oil? Obviously I would still replace the filter. Thanks for any input.

You shouldn't have a problem. Just warm up the engine for 2-3 mins, then suck it out. Mercedes uses this technique.
Search "fluid extractor" on your favorite shopping website, and you'll have plenty of good options out there.

The motor is in a boat, he cannot access the oil pan without removing the engine or creating an access through the hull.

My '98 4.6 happens to be a 4X4, however its probably the easiest vehicle I've ever owned to change oil/filter on.
"I am still curious as to why you would want to?" use a "suction device" too.
IMO draining the oil via the drain plug would have the advantage of removing more of the old contaminated oil. Most dip sticks measure only the highest oil levels & the "dipstick tube" ends well above the bottom of the oil pan. Unless "the suction device" includes a special tube to reach the bottom of the pan I'd think you'd leave a significant amount of old oil inside.

Its in a boat and he can't get to the bottom of the motor..... he can't change the oil like normal.... I kno if you run a engine cleaner that lowers viscosity and use a sucktion with a looooong thin tube it should work fine.... worked for me... don't forget always use 5-20w oil on ford motors

oil change
Thanks for the replies. I was not sure if using the suction method got all of the oil out of the motor or not. The reason I was considering it is the suction method is all self-contained in the jug and just isn't as messy as pulling the drain plug. I also figured if I was going to get it for the boat I would get my moneys worth. 5-20w oil really.

On the truck, I do believe that more of the sludge will come out using the drain plug, and in my experience, pulling the filter usually causes more random oil splashing than the drain plug, on which you can anticipate the stream's trajectory. You're gonna have to get the drain pan out anyway. Plus pulling the drain plug, you can probably drain the oil while it's just a bit hotter, which will get more of the old oil out.
As for the 5W20 vs 5W30 thing, Ford does back-spec the 5W20 for most mod motors including yours, but my wife's Duratec '98 Sable (also back specced) seemed to burn a bit more oil when the dealer put 5W20 in it, and I preferred to use 5W30 in that car especially in the summer, but have always used 5W20 in my '02 E150.
Looks like you're in Texas, so I'd say you're an excellent candidate to stick with the 5W30 in your truck, but if a dealer ever puts 5W20 in it, or if you catch a sale on 5W20, you're fine to use that as well.

Has anyone had any issues switching to 5W20 from 5W30 on high mileage motors?
It took a lot for me to get used to using 5W30 "salad weight" oil in the first place.....
I have a 97 4.6L and a 90 3.8L, are the older 3.8's recommended for 5W20 too?
I've been using 10W30 in the 90 3.8, my 91 7.5, and 5W30 in the 97 4.6. The wifey's 01 Windstar 3.8 specs 5W20.
Right now I have to "stock" 3 different oil weights, and 3 different oil filters....
