HD-30 Motor Oil, 1 Quart, Pack of 6

I love Castrol motor oils, they are the best quality non-synthetic oil you can buy, (at least when I went to factory engine schools). Castrol uses the best chemical blend available on the market to reduce engine heat and friction, they use the finest anti-oxidation and cleaning compounds available, short of Synthetics - and I have no doubts that their Synthetic oil and blends are also outstanding! I use this in all my vehicles when available at a good price and my 1952 Farmall Tractor needs the extra wear protection. Thank you, Castrol, for making such a superior motor oil!

I used to be able to buy this oil in my local Wally world ,but they stopped stocking it . This oil is very good for mowers etc.

HD is not heavy duty it is High Detergent! It is required for some gas powered engines. Not every place carries it so I was glad to recieve the HD-30 oil.

For some reason this oil is getting harder to find. And its always special order anywhere from 9-12 dollars a quart. So when I saw this I jumped on it. I use it in a Cub Cadet rider. Great stuff!

I am glad that I have been able to buy this oil from this same vendor for years. You just can't find it in stores and if you do it is almost twice as much per quart or higher in some places if you can even find it. This is the only oil I will use in my zero turn Skag. I have been using this oil in my mowers for 30 years. I always change oil, OEM Kawasaki oil filter and air filter before start of every mowing season. Have always been able to get many hours of mowing out of my mowers without a problem. Might have to add very little at the end of mowing season. As far as I am concerned this is the best oil to use in warm and hot climates being how I live in Texas and it gets very hot in the summer. I might add that this is a residential property and I mow 2 acres once a week and I mow an additional 5 acres three times a summer. If you mow commercially you will have to change oil and filter more often.

Great quality oil. Not sure why most stores do not carry HD30 weight since we put it in zero turn.

Always been a great product, have used for years in my mowers and tiller. Could not find locally, had to rely on Amazon. Price is ridiculous, thanks joe.

Product as expected. Hard to find plain 30 wt oil im stores. Great way to buy it thru Amazon.
