I have no idea what oil I should use. My friend told me straight 30 weight but that doesnt sound right.

 

Just use regular 5w-30 or 10w-30 like you normally do. As long as you keep up on the maintenance intervals youll be good. In my opinion the high mileage oils are a waste of money and I definitely dont believe in synthetic

(I know a lot of people here may use synthetic or high mileage oils but they arent worth the extra money to me and with synthetics, im not gonna drive 20,000 miles before an oil change. Dont like that idea..)

 

I agree with my friend Volvo.

218,000 on my I6. I'm still using 10w30

 

Thanks for the help

 

My dad is an old school hot rodder and he uses 10w30 too BUT he substitutes one quar of oil for one thing of Lucas Heavy Duty Oil Stabilizer, if you wanted to try that. I use it sometimes but I'm leary about it.

 

What weight would you guys put in my truck. 5.0 with 98,000 miles.

 

10w30 just like the owners manual suggests.

 

or whats factory oil supposed to be, and what would you guys reccommend insted. i always use thr Fl1A oil filter in my 5.0's

 

factory oil is motorcraft 5w-20 and yea the fl1a.... i use valvoline ful synthetic 10w-30 and i have the fl1a on it now but thats only coz i didnt have the cash for a wix filter or a higher grade purilator

 

10W30 good for 460 as well?

 

I carry the same opinion on the synthetic. I used to use it but found no difference. However, I am a firm believer of regular oil changes at the 2k to 3k mile mark. 10w-30 is what Ford recomends.

 

No on the staight 30 , use 10-30 , with 200K , try the castrol GTX high milage 10-30 , it helps keep the old seals lubricated ....Lew

 

while I agree that and 'old' motor should not be switched to synthetic (have heard of low pressure problems), I strongly believe in is benefits .. have a buddy that works for Consumers Reports (he's a mech engineer) and they did a real world test on NYC taxis a while back that proved the stuff is better .. on my daily drivers I change oil and filter every 5k miles (to maintain warranty), no stickers or trying to remember the last change, just change it at even 5k intervals on the odo .. I figure the extra protection if it ever overheats is worth it .. he (the mech engineer) said even just one quart per change would be beneficial ..

 

I have 275k on mine and its never even had som much as a valve cover off. I have been running high mileage oil 10w30 since about 100-120k.

I have been running Pennzoil high mileage, because the truck always had Pennzoil in it for 90k miles before I got it. I don't like changing brands and mixing oils.

I change mine every 3k miles or a bit sooner if it looks dirty.

I would recommend the Valvoline Max Life, Penn high mileage, or Castrol high mileage. I don't think our trucks benefit any from synthetic oils. They are too expensive anyway, and I don't buy the long oil change intervals. There is stilll going to be dirt and moistured that makes its way into the crank case.

Oh yeah, get a Motorcraft filter. If you can't find that then Wix or Purolator. Do not use Fram!

 

I've always put 10w-40 in mine because that's what my dad used in his. Is this to heavy?
