Engine oil Castrol or PENNZOIL

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.

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 flip between Pennzoil Ultra Platinum and Motul X-Clean both in 5W-30 depending on if I order ahead of time online or just go to the store/dealership for parts. Both have been good, just make sure to keep up on maintence schedules and you'll be fine with pretty much anything

I use just regular old Castrol Edge full synthetic 0W-40 in my 2012 Jetta year round, currently has 156k miles on it (251km).

I used both wrong spec oil and wrong weight oil on my 06 Rabbit 2.5 for about four years. I was an idiot. However, nothing ever happened. I'm at 223,000 miles and the cams look brand new, engine runs smoothly.

Castrol works fine.

Smedia had a video about this and he had more wear with less miles using Motul over Castrol in a Blackstone report. So for me just the convenience and price of Castrol edge I'd pick it over Motul. Knowing it had less wear wear was the nail in the coffin of buying overpriced and often several year old Motul.

It is an oil from one of the lowest ranges of Castrol.

It is a 100% mineral oil, which is not good and therefore, in addition to greasing, cleaning and cooling less, it has a much shorter useful life, it needs more frequent changes, it is an oil how little/nothing is worth it for a motorcycle whatever it is.
