It may say diesel on the bottle, but it has many uses. It is a high quality heavy duty oil that is useful in all sorts of small engines. I use it in my generator, mower, ATV, tractor...some people use it in gas engines. It has a higher zinc content which is great for protecting engines. However, that same zinc content could possibly cause problems for catalytic converters.

If you have an engine without catalytic converters, I would recommend T6.

It's been said by some that full synthetics are too slippery for motorcycle wet clutches, but I've been running it in my 2002 Honda GL1800 for many years with zero issues. With oil change intervals at 3000 miles, my vehicle engines stay spotless internally and seem to run forever before showing any signs of age.
Not synthetics, any "Energy Conserving" oil will mess up a wet clutch. They have friction modifiers to improve fuel efficiency.
T6 is pretty big in the motorcycle world. I've used it since day one. I go with 5k mile changes because the US bike world is still avoiding reality. If I look up the EU manual for my same exact bike(same motor) they are at 7k miles intervals so I go for the middle lol.

Are you changing oil on a semi or something? Most cars/ SUVs will take between 4-8 quarts. Even a 6.7 Cummins only take 12 quarts/3 gallons
Ford 7.3 diesel 15 quarts.

Good deal but I need the VW 505.00 for my ALH TDI. I don't see that this one has been tested for it on the back.
This is fine oil for the ALH, that all I've used with 10k-20k OCI and most people use it on tdiclub. I even run is on my 2013 Touareg TDI.

I'm learning a lot about oil today; I have to admit that I haven't gone too far down the rabbit hole of nuances between brands and additives. Motor oil quality has risen so dramatically over the last 25 years or so that even cheaper oil is better than it's ever been. Based on what I'm seeing here, I'll probably switch to T6 for my motorcycle to head off any clutch issues down the road. Happy to sacrifice an mpg or 2 to keep my clutch happy and healthy. The cost difference is negligible when it comes to the oil itself.

Amazon is not shown as an approved purchase location for this rebate; I wouldn't risk it. Walmart ships free to your door as well, and is a sure thing with rebate submission.

I used T6 5w40 for years in various Miatas, a MazdaSpeed3, and other vehicles. It's a fine oil.

But, it's been surpassed, in my opinion, by other synthetics. In particular T6 has shown increased fuel dilution (and therefore decreased viscosity and lubrication) compared to other synths, especially with extended oil change intervals.

I have more jugs of T6 than I know what to do with at this point. I've switched over to Mobil 1 Euro formula, Pennzoil Ultra Platinum, or Liqui Moly (depending on vehicle and availability).

I have a VW ALH with 278,000 miles. Rotella T6 15w40 full syn has been recommended many times for ALH TDi engine which is not nearly as sensitive to engine oils as newer VW TDi engines. The bigger issue is finding a competent mechanic to disassemble the variable vane turbo and clean out the carbon so that the vanes are free and the computer stops throwing faults and limp home mode.

I had my turbo rebuilt for $450 with Garrett parts. Labor was $400 to take it out and clean out the intake manifold/EGR. Now I'm running with the EGR vacuum hose removed and blocked

Well, there is a European performance shop local to me that runs it in their race cars. I usually pick up a gallon of 5w40 when I go to Walmart. It's a relatively inexpensive full synthetic. I'm not a fanatic per say, but at ~$17 a gallon, or ~$4.25 a quart. I'm in for one.

I had a Honda Foreman. Rotella T6 meets the JASO spec for many of Honda's automatic clutches.

Run in my cars. The M54 seems to like it just fine. Quieted the hydraulic lifters versus M1 5w30 that the cars both had when I got them.
