Owner reviews for engine oil

I already added to engine oil and transmission. 5mpg improvement avg. already.

I use the Mobil 1 Racing 4T 10W-40 which is synthetic *and* meets JASO, just because it is always available at the nearby Walmart.

One oil that seems to work from all the videos I've watched for cleaning varnish is the Valvoline Restore and Protect.

I use this on my Hyundai Elantra for the past 100k miles ... It's already at 200k and the engine still feels new ... I use Valvoline for everything including power steering ... Valvoline syn blend is a great oil option ...

Valvoline protect and restore has more detergents than any other I believe to clean out thew gunk. I've been running it in my car for 3 oil changes now.

i own a 2008 chevy colorado(2.9 4cil) and i used to buy all kind of expensive oils for it, nowadays i just use STP full synthetic 5w40 and change it twice a year

I've seen lots of videos showing the Valvoline restore and protect oil helping to clean engines. If you go that route I'd recommend replacing the oil filter after 500 miles then again at 2500 miles to keep the filters new for any gunk that gets freed up.

Change the oil at a minimum, and do it regularly. Use a quality synthetic high mileage oil and change it again in a couple thousand miles, then change on regular 5k mile intervals.

I went to Valvoline once, oil pan emptied itself onto their floors the moment I started the engine. Joking aside I think it's perfectly fine to go to Valvoline, I go there often bringing my own oil and filter, that way I know it's the right oil and it's good quality stuff.

I used Liqui Moly 10 40 for my 3vzfe 96 camry. The car started making a horrible ticking noise coming from the valve cover. Its at 225k miles. The engine runs good but noise is annoying.
