I only use Rotella T6 in all 6 of the cars at my house.
Owner reviews for engine oil
I use Pennzoil Platinum Full Synthetic in my 21 Forester. $23 for 5qt from Walmart and $12 oil filter from dealership.
Have a look on Amazon they do some good deals on oil, I normally stick it in my basket and wait for it to drop.
My old car was Castrol 5w30 Magnatec, £28.50 for 4l on Amazon £43.99 from euro.
I changed my engine oil at 5k km on my own because the bike felt shit to drive, heating up too much + shitty mileage, my guess is that RE uses an improper grade or bad quality oil, i used the motul 10w50 fully synthetic oil, it's an immediate and huge improvement, mileage, heating, smoothness, clutch, everything improved, and I'm not even exaggerating.
Even Ravenol, which is pretty expensive since it is made in Germany from Group V base stock. Great stuff.
Project farm did a bunch of tests on all popular oil brands and amsoil won followed closely by pennzoil ultra platinum. The pennzoil is easier to get so that’s what I use on all my cars.
I've used Mobil 1 in my 2011 Mazda Speed3 for 8 years. My 2019 Bullitt gets Mobil 1 as well. Mobil 1 is reasonably priced and meets the spec required by both cars.
Mobil 1. I've used it in all of my cars. Two of my mustangs lasted until 240k before needing a rebuild.
Mobil 1, my 05 GT with 150k miles on it getting cams a few weeks ago looks clean inside. I've had the car since 70k and Mobil is all I run in it.
I've posted my UOAs on TDIClub and BITOG. The factory fill was additive depleted at 5400 miles. The Fuchs 507.00 in the next fill was good for 7-7500 miles. It might have gone longer, but I changed it out in advance of a long trip. Bottom line is that preliminary evidence is that the 507 oils are inadequate for extended OCIs in the 3.0L motor.
