Owner reviews for engine oil

Castrol 5w30 high mileage performance, keeps the sucker in tiptop shape

My 25 year old Camry requires 5W-30 and I use Castrol Edge. I also put 1 litre of Castrol GTX 15W-40 oil into the mix - it's supposed to have anti sludge properties and also lowers the overall cost.

From my experience with a Toyota echo; does not matter the brand, only the type. My echo was a 10w40 semi synthetic. once she started consuming a little more oil, I was then just filling her up with any 10w40 semi synthetic I could afford. There was no difference of her running on Castrol vrs the mixed bag of what it ended up with, as I always put Castrol as my oil of choice for a complete change.

But personally i like Mobil 1 brand

Have used a few brands, I think it’s running Castrol 5w40 right now.

Castrol 5w40 Euro spec, my car runs better on that than 5w30

I'm over 50 K on my current Amsoil change. I drive my car a couple thousand miles a month for work. I also put Archoil additive in it when I did the change.

I went with Mobil 1 5w-30 ESP. I read around the Bob is the Oil guy and that is what I came up with what I would best for WRX that will be tuned with an intake (My opinion). I am sure there are other good options.

I had the same issue on my 2019 A6 3.0 last year. Two times I had to pop into the dealership to have oil removed (no charge) and the issue was due to dilution and short trips.

The new LM MolyGen or whatever it is called is not as good as the oil that was discussed thoroughly in this thread. I strongly recommend you stick to the LM Leichtlauf (part number 2332). If you engine sounds \"angrier\", and if that's not in your head, then that is a bad thing.
