What certified over the counter synthetic in the 5W-20 weight is showing good results in both oil analysis and user feedback?
Thanks for the help.
Any of the name brand oils( Mobil, Pennzoil, Quaker State, Valvoline )you can get in bulk jugs at Wal-Mart will have the correct weight and certifications you need( sometimes hard to find 5W-20 in all of them at Walmart in the 5QT jugs but the oil companies do offer it ). Any of them would be a good choice.
Another good choice would be Kendall. They offer a blend and full syynthetic that are very affordable and very good in 5W-20. Meets all of your warranty requirements as well. I have recently been converted over to the ConocoPhillips mfg'd Kendall oils. Have a few family vehicles running it now and they are doing great on it. They are using the GT-1 full syn. Just @ $4.99 a qt from PepBoys.
Also, just FYI, Amsoil offers a 5W-20 that meets your warranty requirements. It is in their XL line. It has the correct API certification you need and I have no doubt it meets( probably far exeeds )the Chrysler MS6395 oil standard. IF you can get it for a reasonable cost it will be goood for your OCI limits and would be a good choice.
