Owner reviews for engine oil

ever since 15,000 miles I’ve been using Mobil1 0w40 and Mobil1 oil filter every 5k miles. I’ve used it on both hot 80-100f summer temps and now on winter temps. Haven’t had a single issue. When cold I can tell how the engine revs down quicker since oil is really thick so I couldn’t imagine the 5w. Still it’s been running for more than 50k miles on the Mobil1 0w-40 and it’s been great.

Running the OE Castrol 0w-20, pushing the car very hard up a twisty road in NC/SC, I saw a maximum of 235F with an ambient temp of 75F. My averages with normal driving are close to yours. These temps are well within the oil's capability.

The accord gets regular mobil 1 from walmart.

Rotella T6 is a great oil for these cars, and it's what I use.

i been using it religiously for now 85k miles, i have tried Quartz Ineo 5W30 502 Spec oils made my engine produce more heat and valvetrain noises. The Castrol Edge 0W40 I use now tops out at 212, normally sitting between 205 and 210. With the 5W30 Quartz it was constantly sitting at 227-237 which is pretty significant.

this oil is my most trusted, been using it since new with the best results ( i tried Mobil1 0W40 and a 5W30 Total Quartz once each and oil temps were 15-20 degrees hotter in similar ambient temps and conditions with both of those so i decided not to use them again).

I use Mobil1 0w-40 and a Mobil1 filter. Haven’t had any issues. I’ve noticed that when my oil intervals where more far apart the engine would idle at 1,400rpms then feel like it raises it and lowers it like some of the sort. An issue that goes away once I put fresh new oil in everytime. It doesn’t interfere with the engines performance or anything but it’s something I notice on cold starts.

I originally ran 10k intervals as recommended by VW. Early oil changes were done with Castrol Edge OE 5W-40(exact same type the dealership uses) Later on I thenswitched to Liqui Moly 5w40 Leichtlauf high tech and began running at 5K intervals after reading quite a bit about the 10k intervals being too long.

Although this is exact replacent, mazda OE still uses Mazda branded GF-5 which is exactly the same oil but branded Mazda....

Love these high molly low viscosity oils. Absolutely the best out there

I've used Mobil1 many times but my last oil change I decided to use Valvoline 5W-40 MST SynPower which is actually on the list as a 502.00 oil.
