I had read around on the forums about this oil being used in motorcycles sominthought I'd try it out. It is JASO approved which means its good for wet clutches. This is a full synthetic and it only ran me $17(on sale) for 4 quarts! Great deal!!! Works great, and I've noticed a much smoother ride and better shifting since the change. If its made for diesels, I know it can handle my CBR600RR

This oil is made for hot running engines and we know what heat does to things. Many Harley Davidson riders have gone to this because it has all the protection that an air cooled engine needs. We all know how many miles a diesel truck puts on the road while delivering across the nation and how many times we have sat behind one waiting. Heat is the enemy of oil and keeping the engine parts slick is long life for the engine. When you start that engine for the first time in the morning it has parts that need to be coated and slick... that's where Rotella comes in and it adjusts through the day's temperature and the season temperature. Engine manufactures have determined that it should be changed at or around the 5,000 mile mark.

I think that this one of the best oils on the market for trucks like mine as well as all of the new ones being built today. Why should we not use all of the newer oils to make our older Diesels last longer, if they help the new trucks, they should really help our older trucks that have some age on them and are still being used every day, for work, pleasure driving an just to have around. Mine has 268000 miles on it and I hope to put a Million Miles on it, if I live that long.

This is an excellent product. I only took 1 star off; as I'm not sure why Shell is the only company that sells 4 quart (1 gallon) jugs. Most vehicles take between 4-5 quarts. So I end up having to buy two of these gallon size jugs, just for the extra 0.5 quart. I'd be perfectly fine, if they made 5 quart containers and raised the price to $28.09 (which is still $5.62 per quart). As far as the oil itself, it is excellent oil. Although, it's not officially approved by VW; many folks have used it for hundreds of thousands of miles with zero wear on the camshafts of these PD engines. I use it on my 2006 VW Jetta TDI (BRM) diesel motor. I've used for about 20k miles and I change my oil every 5k miles. The oil itself seems to perform very well.

Using it in a semi tractor with cummins engine, with this oil and a bypass oil filter, i can extend the oil changes to 100,000 miles, well i do a oil test everytime i change bypass oil filter (every 10,000 miles), and so far the test returned showing oil in good condition.

Used T6 in my 2007 FZ1 since I bought it used about four years ago. I rev this bike to the Max, never had a single engine problem, doesn't run hot, uses zero oil in between changes. I understand that it shears easily in a wet clutch situation (as do many oils) so I change it as I reach about 1k or 1.2k miles that way the engine always gets fresh oil. It's cheap and not that hard to change oil and filter. I only ride for fun so I change it maybe a couple of times a year.

After reading the reviews on this, I tried this in a 2001 YZ250 and a 2004 TTR225, both shifted hard after using it. I tried changing it again in the YZ250 and it didn't improve. I then returned to the previous brand, Valvoline 4 cycle Motorcycle oil and the shifting problem went away. Now the bikes easily slide into gear.

This is a truly excellent oil that has the ratings and approvals for all my vehicles, gasoline, diesel, air and liquid cooled. Rotella T6 is the only oil I buy for my cars, trucks, tractors, ATV's, UTV's, ZTR's, gasoline and diesel powered generators, a power washer, log splitter and other small gasoline, air cooled engines, basically everything except 2-stroke gasoline engines. I love only having to buy one engine oil.

I have been using ROTELLA Full Synthetic for 10 years in my Honda ST1300. I Change it every fall when putting the bike away for the winter. I have 180000 km on the bike. It does not burn a drop of oil. This bike is not a stranger to the far side of the speedometer.

I've been using T6, 5w-40 in my Terex diesel mini-excavator for four years. Cool runner and easy starts in cold weather. No engine problems or abnormal noises. Price is good with the rebate program. As an aside, I'm wondering if the motorcycle guys may have a "wet" clutch which normally requires a NON-synthetic oil.
