Had this tractor for 45+ years. It's been good to us. Having had good results with Triax in our other vehicles we decided to treat "Ferdie" to all Triax fluids. Noticed the same results as we did with our other equipment and vehicles. Smoother operation, quieter, stays cleaner longer.
I'm a Red Line oil convert, good product but pricey. Triax products deliver superior results at a fair price. 5 Stars.
pours so smooth it had a small tick noise but now its so quiet ill run this in all my mowers
Satisfies the multi weight issue. Heavy duty without the oil stiffness at cold start
Just made the switch from Lucas to Triax in my zero turn. Used the Power 4-Stroke with 7% S7 for the initial oil change. After performing a 6 hour mow job and due to finding that an incorrect oil filter was installed on the engine, I had to drain the fresh oil to install correct oil filter (32 micron to 20 micron). What I found was that the Triax with S7 cleaned the engine beyond belief. I routinely change oil yearly and never once thought my engine was becoming dirty. I am just your normal home owner with a huge yard and my small engines get used hard in a years time. Let this be proof that what Triax claims as being top shelf oil with a detergent package that cleans and restores engines has been 100% fact. See for yourself the before and after pics of the first oil fill with Triax and the oil after 6 hours of hot mowing then oil changed due to an incorrect filter!
It gets really dusty and hot here in summer, I service many small engines that see 200 hours before they come back for oil changes. Put this in my personal mower, pressure washer and generator so far and its working out nicely. Wish the buckets came with a spigot for easier dispensing. If it sits use a drill and paint stirrer to re mix the additives!
I do lawnmower repair and this is my go to oil. This is my third year using it in my small business. I buy the 4 pack but now they started selling a five gallon pail which will be my next purchase. Excellent product, fast shipping.
I started out running this in my generator because of the advertised extended change interval. The manufacturer wants me to change the oil every 40 hours of operation, and I've been using this conservatively for 100 hours with no issue. It seems to come out cleaner than other oils as well.
The cherry on top is that it works in applications calling for 5w-30, 10w-30, or SAE30 regardless of temperature. So I've since started buying it by the gallon and use it in all my power equipment in all weather, taking full advantage of the extended change intervals.
Add to that great customer service with thorough answers to my questions that lead me to this strategy, and you just can't beat it. This is a great company making a great product, and I hope they stay that way!
Way less sludge in our commercial mowers. Our gear runs from 7 am to 8 pm in the summer, run em hard. Seems to be an excellent product, we also use the TRIAX zero turn tranny fluid, outstanding product too.
On the ranch, we have a couple zero turns, a lawn tractor, 2 mobile welders and countless other pieces of equipment that have small 1cyl engines. This is our choice, because TRIAX has treated us so well.
