Seen someone recommend this oil. Glad I did. Engine is running smoother.
The only oil that I trust.I’ve been using it for years now.
First time using Triax products. Love these products. Just did 50 hour service on my tractor and used the gear oil, engine oil and hydraulic fluid. Love these products packaging, shipping was a breeze. Had a small issue with one of the hydraulic fluid pails leaking during shipping(not any fault of Triax) emailed them and sent me a replacement no questions asked. Awesome customer service. I would definitely recommend these product.
Love the triax products for my tractor. Everything runs smoother and quieter. Will use triax again when needed.
I used this for the 50 hour engine service and man is it ever so smoother. Cold starts are much quieter than before and the engine is a lot quieter.
no problems running this 200 hours in a 5045 deere :)
