have been putting syn. blend in my f150 want to go to the old conventional oil which i`ve heard is ok what do you guy`s think - it`s the 2013 with the 5.0 and has 25,000 miles

 

With oil the more important issue is to religiously stick to a maintenance schedule that includes also changing the filter.

Type, brand, etc. are outweighed by the above.

Me ... Have always been a conventional oil (Pennzoil) user (~50 years). Started using multi-grade (5W30) in 2002 with the purchase of a 2003 Crown Victoria - has 120,000 miles and according to the last BlackStone oil analysis shows no wear. Same holds true for 2011 F-150 5.0L with 30,000 miles.

yes i change my filt. every time i change oil which is every 3,ooo - i was just wondering about goin to conventional oil but THANKS

 

I've done it in 2 vehicles, I've mixed the 2, and I've mixed weights. Both vehicles still run great. One I still own the other I've sold.

You'll find on these forums lots of people really over kill it when it comes to oil recommendations.

If anything at least stick with correct weight required.
