Need advice on substitute for Chevron 1000 THF

My Mahindra 7520 specs Chevron 1000 THF for the transmission/hydraulic fluid. It's very hard for me to get in my area and I would like to use something more readily available, preferably something I can order online. (The NAPA website says they carry Chevron THF but when you try to check out, they don't.) This fluid lubricates the transmission, wet brakes, wet clutch, and acts as the hydraulic oil. I called Mahindra and asked what else I could use, but it's a call center with people reading manuals, and they said what is specified are the only options. I found this website that lists equivalent fluids: https://petroleumservicecompany.com/chevron-1000-tractor-hydraulic-fluid/ According to them, there are many options that are "equivalent." From Sunoco TH fluid which is only $41 for 5 gallons to Phillips 66, Kendall, Mobil, BlueSky (at $153 per 5 gallons). The main thing is I don't want to put in some other oil and regret it, because it starts screwing up O-rings, or making my brakes or clutch slip, etc. Checking the specs of Sunoco TH vs the Chevron THF they are quite similar in their described usage, viscosity, and pour point. The flash point is close, but lower, Sunoco at 200C while Chevron is 235C. Here are links to these specs: https://cglapps.chevron.com/msdspds/PDSDetailPage.aspx?docDataId=77320&docFormat=PDF https://petroleumservicecompany.com/content/pdfs/Sunoco-TH-Fluid-J20C-PDS.pdf So what's the reality here? Mahindra tractors are sold all over the world, and surely they aren't all using Chevron 1000 THF. My gut tells me that I can substitute this Sunoco TH without any problems, but I don't want to do it and then regret it. Thanks! Jon

Look for the J20C & J20D John Deere spec. Chevron Synthetic all weather THF is one example. Your John Deere dealership can look after you with their own branded products.

I'd go with some John Deere Hy-gard or Mobil Mobilfluid 424. I have personal experience with mixing 1000 THF and John Deere Hy-gard (J20C) with absolutely no issues. I use THF 1000 in our Massey tractors and John Deere Hy-gard in our JD tractors. I try to stay with one or the other, but have no reservations about mixing them if need be. I just bought a 5 gallon bucket of Chevron 1000 THF, it was $59.50 + tax locally at a local Chevron distributor. I think the last 5 gallon bucket of Hy-gard I bought at a JD dealer was about $70. I am using 1000 THF in an ATV that calls for Mobilfluid 424. The 1000 THF has been in there for over 4 years with no issues. https://crossimplement.com/file/156/John%20Deere%20Oil%20Guide%202019.pdf https://www.shopgreendealer.com/Joh...draulic-Oil-5-Gallon-Bucket-AR69444.html https://www.mobil.com/en-us/commercial-vehicle-lube/pds/gl-xx-mobilfluid-424 https://www.summitracing.com/parts/...dU69a2QF9oguYA9auBQw-usTps0aAoHDEALw_wcB

J20C = Yes J20D = NO!!!!! That's low-viscosity I think any AW46 equivalent should be adequate.

Hi LeeVing, I tried the NAPA page for Chevron THF 1000 and it worked for me. Maybe give your local store a phone call and they might be able to order it. Sometimes computers have glitches. Also check and see if there are any distributors in your area. I'm somewhat picky about tractor fluids. TractorByNet forum has quite a few discussions about Mahindras and Chevron THF 1000. Some members claim that their Mahindra manuals show alternatives to Chevron THF 1000. This seems to be run of the mill conventional fluid, so I think your hunch about the equivalent fluids you researched is correct. Any fluid that meets the John Deere J20C or Kubota UTD spec. should be fine. If you were needing a synthetic all weather low viscosity fluid for a hydrostatic tranny I would tend to be more careful. Good luck with your decision. I've had, and heard of problems when using the wrong fluid, so it is good to be detail oriented about these decisions. https://www.google.com/search?q=chevron+1000+thf+equivalent+site:www.tractorbynet.com

Usually the proper specced oils from a major oil company will be fine. Chevron .Shell. Mobil etc.
