I have a 2007 XL brand lowboy trailer, I need hydraulic fluid suggestions I just rebuilt all the hydraulic system, new seals in all the cylinders, new hoses, new filter. The reservoir is empty as well. Anyways the manufacturer suggestion is ISO32 hydraulic oil but I’m afraid it will have bad...

I’ve been using DXA for a few years with good results but it always had this peculiar smell to it for the first 3-5k miles. I noticed that it doesn’t have that smell anymore, I can’t really explain it but it was sort of a foul smell that I was used to. Does anyone know if they blend has changed...

Still having viscosity issues that I can’t figure out how to fix. But otherwise I think it looks good. Any input?

Alright I have a dumb question. Has anyone else experienced this issue. Rebuilt my 60 series 300k ago, out of frame. And ever since the bellhousing gets wet on the transmission. The weird part is that it’s usually only the seam where the bellhousing and rear structure are mated with the...

This company has been hitting all the local trucking companies around me. Switching their grease over and trying to switch over oils. Besides their website I can find very limited information on it. I’m currently using Phillips 66 multiplex 600 for a full chassis grease and their claim to fame...

I just bought this 2016 flex 3.5NA car for my wife. It just rolled 100k and I wanted to stay on the PM side of things. I know the water pump and timing chains are issues with these engines. I was contemplating doing it myself. I am mechanically inclined and feel confident doing the job. I’m...

Just bought the wife a 2016 flex AWD with 100k on it. To my knowledge the PTU has never been serviced. I was recently told that these cars cook the oil and create sludge inside. I was wanting to change it but do some kind of flush as well if it’s a good idea. Thought process is this. Drain it...

The engine has about 170k on it now. And it’s still shearing oil. I’ve had numerous UOA’s done which I can post from Blackstone and one from Polaris. The engine doesn’t have a dilution issue. So it seems to be coming down to heat even though the oil temps never go over 215 and that’s when the...

Changed oil yesterday and I had an older jug of chevron, maybe 6-8 months old and a newer jug, 3-4 months and they were completely different consistencies. The older oil was thicker and heavier. The older oil was in the old jug they been using for 20 years. The new oil was in the new style jug...

My buddy in Australia mentioned when they turn up their series 60 engines they run a 20w50 oil. But they don't see the temperatures in the Winters like we do. I'm not familiar enough to make this decision, but in cold temps, -10 on up would 20w50 be to thick for my engine in the states?

So I'm running a 2004 series 60 engine, non egr, non emissions engine. Running Phillips 66 15w40 fleet supreme during the break in period. I built it last January, got it installed and ran it 13k miles and grenaded it due to a typographical error on my part. Anyways, rebuilt it, fixed what I...

I buy my oil from a local distributor, this hasn't been an issue yet. But today I pumped 5 gallons of 15w40 fleet supreme into my series 60 and found particles at the bottom of the bucket. I called my rep right away, he said it happens on buckets that have been sitting and it's ok, but I...

This is NOT my engine or sample.. I'd like feedback on this. The engine is running the OPS bypass filter system, she'll rotella T6 and T4..I know a lot of details are missing. My question is the elevated oxidation levels. Is that bad?

I was recently at a machine shop, the owner mentioned this to me and I've never heard of it. My new engine grenaded after 13K miles, no fault of anyone but myself and surely not the oil. Anyways, this new engine will be all new internals again. But when I built the last one I put 15w40 Guardol...

I've done a lot of reading in here and come to read that the liquid titanium in kendall is no longer, however I can't find anything in relation to they're HDEO. Does it still retain the liquid titanium? How does the liquid titanium work with new engine break in? Everything I'm reading states to...

I posted on another forum and forgot about this one. Building a Detroit diesel series 60 engine. I've had 2 suggestions when building. 1. Use an assembly lube on the main, rod, cam bearings. Specifically lubriplate 105 was suggested. 2. No assembly lube, use a pressure primer before you...

I'm finishing my engine and have a couple questions for the oil guru's..I've used chevron 15w40 religiously in my trucks for 20+ years. I'm now (cause of this forum) looking at oils in a different manner.. My question revolves around what things I've been reading. I know a lot of things can...

On my tractor trailer I'm looking for a great option for a chassis grease, brake cams, u-joints, spring pins and so on. A GC-LB grease. I'm currently using mystik JT-6 #2 w/o moly high temp, red tube, red grease. Reading from a lot of people's opinions is why I chose it. I'm needing to buy a...

The local oil company has their own brand of oil they sell, proguard, I find little information about it. Their sales guy has been offering it to me, because it's house brand of course, but whenever I read any data sheets a lot of the areas for testing says "data not available." I don't see that...

I currently run Chevron esi 80w90 in all my gear boxes. I'm thinking of going to a full synthetic, maybe a 75w-90 or 75w-140. I spoke to Chevron about this oil and was told by their tech cause it contains a special additive package including boron, he wouldn't elaborate stating it's proprietary...
