What's best for my 2018 MF1726E--Synthetic oil? Synthetic blend? or regular (good quality) oil?

Thnx...

What does the owners manual or dealer recommen

 

[TVZ]

The manual does not specify whether synthetic or other is best. It just says to use 5W-30. I thought I might get an answer from someone knowledgeable here...

I would use Rotella T6 synthetic.

I see. Hopefully someone will give a knowledgeable answer.

Opinions vary on synthetic vs. blend vs. regular oil. Synthetic oils generally excel in extreme conditions and environments. With modern machinery it is much more important to use the correct API rated oil, particularly with recent emissions equipment.

My personal preference has been fully synthetic oils for many years. YMMV

5w30 is what I used in the VW TDI for near 7 years and near 70k miles, changed every 10k miles. Used same 5w30 Castrol from VW dealer in JD 2025R and Isuzu generator. Can get 0w30 M1 EsP from Advance Auto now. That's what is in the 2025R now.

If you check with a distributor I think you'll find 5W-30 is a synthetic blend whether it says so or not.

I use Amsoil 5w 40 on my 1423

Why is this still a question in 2021? Use synthetic, be happy.
