I have a Kawasaki 600v on a stand-behind zero turn mower. It runs great but is tough to start without starting fluid. I bought used recently so I don't know the history of how long it's been doing this. One quick shot of starting fluid and it fires right up. What could be causing this, clogged jets?

This OCI was with 5qt of Castrol Edge EP 5w30 and 1qt of Castrol Edge 0w40. My goal with the mix was to beef up the viscosity just a bit since this motor is known to thin down oils with dilution and high heat. Looks like it worked compared to my last run of Castrol 5w30 (First UOA).

70/30 Highway/city mileage on this run. It's smooth stuff which has been my experience from Valvoline. Not liking the iron even though I know it was not bad at all. I like that it stayed in grade and didn't use any oil. Long highway runs up and down FL coast for work. Would have like to see Iron...

First UOA on our Mazda6 that currently has 178k miles. This car runs like new and I've only had to change fluid, brake pads, and spark plugs. I did the first drain n fill on the transmission at 160k, I was going to test this lifetime fill concept but I caved. No issues with transmission so far...

First UOA on my F-150 and I’m pleased with the results. About 80/20 city/highway. I work 4 miles from home. Mostly short trips, some off roading, and a little bit of towing about 6.5k lbs. I didn’t expect wear numbers this low, even for the short-ish 5k run. The additives referenced was Chevron...

Has anyone personally tried Amsoil ATF in lieu of the crazy expensive Acura 3.1 fluid? I'm tempted to try it but looking for someone who has first hand experience doing so.

It just seems like on paper/in theory it makes a lot of sense. They're notorious for beating American full synthetics out of grade, although Castrol and PP seem to hold up decent. Those oils probably have a HTHS of 3.1 - 3.2. I'd trade an mpg or 2 for some added protection/longevity, especially...

I ordered 3 Motorcraft filters at different times from the same Amazon Prime link with high reviews. They are FL-500S for a 3.5 Ecoboost. One looks completely different from the other 2 and I'm wondering if it was a Motorcraft design update or one of the types is fake. The main difference is one...

I'm a long time lurker on here. Haven't posted in years. Recently bought some Mos2 on a whim just to try it out. I will say, after 1 day. You definitely can feel the smoothness everyone talks about. And it smoothed out my idle a bit. At least by 50% or more. I have a rough idle in a 2001 Nissan...

I've done a google search and this sounds like a common issue with lots of people asking about it. However the responses I've read are inconclusive. I wanted to run it by the BITOG community for hopefully some better expertise. The oil light flickers when the engine is hot and the oil thins a...

This winter I ran PYB 5w30. It was a pretty cold winter for Florida standards. My motor does the usual start-up tick for a second or two before the hydraulic lifters pump all the way up and then its gone. I noticed this winter when it would drop down in the low 20's that it wouldn't do the...

I recently had a lifter and rocker arm replaced and the mechanic said my cam lobe is worn past the hardened coating down to the softer metal and my time is limited on that camshaft. I want to know what metals would show up excessively in a UOA if the cam was wearing like he said. -Nick

I live about .2 miles from work. So I obviously never get the engine/oil up to temperature. Is the occasional 30 minute trip in the city as effective as the much needed 30 minute highway trip to burn off contaminants/fuel from the oil? Light traffic, no excessive idling beyond a few lights.
