Description

Various environmental factors, such as subpar fuel quality, hot weather, and stop-start driving conditions, can have detrimental effects on your engine. The accumulation of sludge, varnish, and carbon build-up due to these factors can significantly reduce engine life, power output, and fuel economy. Castrol Ultraclean is a synthetic blend engine oil available in 0W-20, 5W-20, and 5W-30 grades. Its unique double-action formula has been scientifically proven to effectively cleanse and remove sludge that can obstruct vital engine oilways. Additionally, its advanced synthetic technology aids in preventing the formation of new sludge. In fact, it offers up to 1.4 times superior sludge protection compared to the latest industry standard. When it comes to maintaining a clean engine, no other oil can rival the performance of Castrol Ultraclean.

  • Best price best product.

  • Best Motor Oil for Easy DIY Oil Changes!
Size: 160 Fl Oz (Pack of 1) Style: 10W-40
I recently used this to change the oil in my 2010 Subaru Forester for the first time. I was a bit nervous, but this product made the process simple. First off, the oil itself is top-notch. My car runs smoother and feels more responsive since the oil change. The engine noise is quieter, and it seems to be running cooler as well. The performance improvement was immediate and very noticeable. The 5-quart container is also very convenient. It has a sturdy handle and a secure cap, which made pouring the oil into my car easy and mess-free. After I refilled my car, I used the same container to hold the old oil. It was great not having to find another container for disposal. I couldn't be happier with Castrol GTX. It made my first DIY oil change a breeze, and the results are fantastic. If you're looking for reliable motor oil, I recommend this product. Five stars all the way! ... show more

  • Good price
Size: 160 Fl Oz (Pack of 1) Style: 20W-50
Shipping was a little slow, but no unduly so. I will use it to change the transaxle oil/filters in my Snapper Pro. Castrol works well.

  • Motor oil
Size: 1 Qt (6 Pack) Style: 5W-30
This oil is great. I use it for all of the vehicles I've had. It out lasts conventional motor oil considerably. It performs better than conventional. Easy to service at least for the truck I have.

  • Decent price for a good lubricant.
Size: 160 Fl Oz (Pack of 1) Style: 10W-30
Bought it in bulk which comes in lower than the parts place that sells it for the same volume.

  • A good engine oil for older cars.
Size: 160 Fl Oz (Pack of 1) Style: 20W-50
Have been using this for my old 1987 model car since 1990...I have resist switching to synthetic or semi synthetic because I do not want to take a chance on engine leaking. This was a problem on early synthetic and I read that the newer synthetic do not have this problem anymore, but why take a chance.. The 5 quarts are a good value when they are selling for around $25, but it seem the price has went up. Not sure I will buy them anymore if they are the same as buying the 1 qts, since I have to use a funnel for the 5 quarts due to clearance on my rear engine car. ... show more
