Penzoil Ultra or Platinum who has used it?

Several people on a forum for one of my previous cars noticed that their engine seemed louder with Mobil 1 than with other brands, even when using the same viscosity.

That is complete BS.

Nice way of replying.

I was not directing that comment to the person who posted in this thread, rather to the person who originally posted it in the other forum. Sorry if I was not clear about that.

Need to change my oil tomorrow, Have my OEM filter and need to get oil, Normally I use Valvoline SYN for some on my cars 10/30 and John Deere plus50 in my Ford 7.3TD 15/40 and tractor 10/30, Mobil 1 in 09 EVO 10/30 and 88 T bird 2.3 turbo 20/50.

I'm looking for a better oil or I may use the John Deere Plus50 as I buy it by the 5gallon jug.

So this is a loaded question.

Thanks

The John Deere oil is formulated for diesel engines and has different additives. Any brand named oil for gas engines should meet or exceed the oil specs the manufacturer recommends. What your owner's manual says
API Service Sm/ILSAC GF-4 or above. SAE 5w-20, 5W -30, or 10W-30 if normal temps are above 0
