Castrol GTX High Mileage 10W-40 Synthetic Blend Motor Oil, 5 Quarts, Pack of 3

My Pontiac Grand Prix has 220,000 miles and I’ve been using this oil for years. She continues to run great! If I could only make all the rust dissapear… haha!

great price

Good price. Delivery quick.

Best motor oil you can get. Great price also! 5 stars!

Why did you pick this product vs others?: Best oil ever. I use it in all gas engines and zero complaints fir 50+ years

Full synthetic oil tends to run low after a few months on older engines. Also, as an engine ages, the 5w20 also becomes a little too thin, causing it to also run low. So.... I've found that running 10w30 synthetic blend lubricates my 300,000 mile engine just fine without having to add the extra quart between changes. I prefer motorcraft, but it no longer comes in 5 qt bottles, so here we are. It works great for older engines that use a little oil (with 5w20 synthetic).

I've been using this oil forever and it always holds up without any sludge. Luckily the price is still affordable. I can't believe the auto parts stores won't $35 for a jug of this.

I've got a 2010 Prius with 200k miles on it. It's been drinking the 0w20 full synthetic, so I've been trying various oil weights for a while. So far, I really like this 10w40 Syn Blend. I've towed 2 times and driven a smidge over 1000 miles and only burnt about 1 quart. Which is super low. I would have burned about 3 quarts on 0w20 full Syn. I do like this 10w40 a lot, but I have been using the 20w50 as my top off oil. So far I've only used about 1 quart of it. (4.4quart is all the car takes) I'm down in Texas. It's up in the 100Fs in summer and last winter, it go in the 16F area and I was quite worried. It seems like it's been ok, but I'd try not to do that very often. I tried to get oil flowing by repeatedly starting and stopping the car. Oil color!!! With 0w20 full Syn, I would go 400-500 miles and my oil would go from clear, to super black! This oil out of the can has a slight brown color to it, even though it looks blue as you're pouring it. It really hasn't changed color at all, at 1000 miles.
