I prefer mobile 1 over other brands because it tastes better and keeps me regular. That, and because I've been using it in my personal european cars and customers vehicles. I've never had oil related failures of turbochargers or other internal components when religiously running this oil. Even the Audi 2.0t FSI cam followers last longer

I've been using this oil for over two years now, first time I've seen it on Amazon for less than it's at Wally World and it gets shipped to my front door! How good is the oil? Consider this, I do oil analysis on a fairly regular basis through Blackstone labs and I've tested this at 5K and 10K miles (it was changed out at 10K). At both

This is the only oil I use in my 2004 dodge ram 1500. It wants 5w-30 in the manual so that is what I buy. I live in North Dakota, so it is used in my pickup during very harsh winters. I change it at 5000 miles now that I drive a lot and it doesn't look terrible when I drain it. I used to do 3000 when I would only put on 3k a year. In my

Newer Toyota's running synthetic oils are supposed to go 10K miles between oil changes per Toyota. I still try to change it around 4-5K miles. I have loved Castrol since the 80's and this is the first car that I have owned that needed a 0W20 synthetic oil. This synthetic Edge oil is great... the engine is a bit quieter and the oil

It's good oil- if you look at reputable sources which have independently tested this oil, they are all complimentary. There are so many urban legends about oil and so many anecdotal stories from people, it's just bordering on ridiculous mostly.

Attach it to a funnel to easily reach the transmission fill port.Drain the old fluid into a clean container, then

From everything I've heard about the Pilot, the transmission is the weak link in an otherwise reliable vehicle. It is easy to forget about the tranny, we check our engine oil regularly, air filter etc, and neglect the most important maintenance item there is on the Pilot! Honda recommends a 30,000 mile service interval, but the thing is,

Started using this Shell Rotella T6 oil instead of Mobil1 when I noticed that I was losing more oil between oil changes. From the few popular Subaru forums, they seem to have a consensus that the Mobil1 is too thin and gets past the turbo seals and gets burned off as a result. Started using this and definitely have noticed less oil

It's hard to review oil without access to the lab test results. I mean you put it in the engine of your car and your car still works, great. Not much to review. You'd have to set up two identical cars with different oils and run them for 100,000 miles to do a proper test at home without specialty test equipment. So for my review I'm

The oil itself is good enough. Giving a two star rating because there is no clear visibility strip on the side of the bottle, so that you can tell how much oil you’ve poured into your engine.The fluid level markings are there, but they don’t do you a whole lot of good without being able to see where current fluid level.

Once upon a time, my car (which I inherited at 120,000 miles) had a significant amount of piston slap during a cold start. After it warmed up, it would go away.

I have an early 2000s Subaru with about 130k miles on it. I started encountering a rough idle in the spring of 2018.

I am a contractor driver. I drive 120,000 miles a year in a minivan delivering automotive parts. I tested all major brands at Blackstone Labs and found no difference between the full synthetics even Amsoil. So I buy Castrol because it is the cheapest right now. As long as you get full synth, you're golden. Stay at or under 10k intervals.

Stop going to the lube shop with a coupon. Your typical oil change coupon will have fine print.
