Should I use conventional oil, or synthetic oil in my tractor.

[Robin Veerman]

You sound like someone that still does oil changes every 3k miles…

I have heard the stories back in the 70's and 80's about synthetic ruining engines,
I never saw one that it did.

i have nothing against synthetic oil and i do think it’s superior… but from what i heard it seems like the early synthetic oil wasn’t great. I have heard many old timer like my grand father bash synthetic oil left and right many people try to explain that the synthetic oil from back in the day is not comparable with what we have today. I heard stories “like i open the oil pan of that old truck ( it was pack for a few years with synthetic oil ) and their was rust all along the edge of the oil level and none synthetic wouldn’t have done that I never seen that of my life and synthetic oil dosent absorb or mix with water like normal oil dose ….

With that being said when i hydro flood a engin like my quad my first two oil change is with regular oil because it’s cheeper and because of these stories once my oil stay clean i put synthetic oil back in.

It was bad back in the day, but here we are all these years later, it has too have been fixed and made better.

I am pretty sure that when I bought my tractor in 2017 it came with 15W40 dyno. I am up north in Canada. The tractor model that I bought was having turbo issues up here (basically blowing up) because the oil was too thick in the cold. The manufacturer then recommended 10W30 which I am told produced less problems. Regardless, at my first oil change (50hrs) I put in 5W40 synthetic and have not looked back - I have 560hrs now. Back in 2018 (and still today), the dealers mechanic said "good call" on my part!

I always tell everyone that turbo can overheat and break down, but nobody seems to believe that...

15/40 vs 5/40? ever pour or add the former oil that's been sitting out in 25 degree temps or less?
that alone sold me on syn 5/40

I have not bought a drop of dino oil in years, have no intentions of buying anything but synthetics,

Depends on the season.

Summer = Dino

Winter = Synthetic

Pro/Cons to both and it will be a never ending story till the cows come home. Followed lots of this on the, Bob Is The Oil Guy. Thus, my conclusion with the above. It answers the ability to be more on the Pro side seasonally.

Also do not use synthetic blended oil in bottles or jugs. It's all marketing HYPE. Does any bottle really tell you the percentage ratio of the blend? Thus, there is no way any of them can be consistent either with the blending. There is no API standard for blended oils like that either.

But it tells you everywhere to use one or the other, not switch back and forth...

I just love these oil threads! My humble opinion is that people spend way too much time fussing over one type (synthetic vs non-synthetic), brand (Shell vs. Amsoil vs. Super Tech), weight (10W-40 vs 15W-40) oil being slightly or vastly better than another. The reality is that oil caused failures are pretty darn rare, and often oil is blamed for failures when other factors are the true cause. If the failure is due to oil, the primary cause was still likely to be gross neglect or ignorance.

That being said, synthetic is indeed better than dyno in almost every respect (not every respect), and is probably most always a better choice. That holds true for old or new engines. Changing back and forth, and even mixing them, although not recommended, isn't nearly as catastrophic as some people would leave you to believe.

I use synthetic oil. Change it at 400 hours or less. My dealer also recommended synthetic. I discussed this specifically in relation to using Rotella T6 BEFORE I changed from Kubota engine oil. He did say that because synthetic was thinner, some tractors may show slight leaks. His last statement was, you can't get any better oil than T6. I think he was right, because we can't get any T6 now. Ha. I have 3 extra gallons.
