Engine oil Castrol or MOTUL

BMW has been endorsing Castrol since the early 1990's and I have to say that I've never had anything but good results using Castrol. I think it is a great oil and seems to do really well in BMWs.

Hey! I had two Octavias with the 1.6 TDI: the mk2 (I sold it) and the mk3 (the current one). Personally, I prefer Castrol Edge 5W-30. On the mk2 I once used Ravenol and the engine was a bit noisier compared to when I used Castrol.

Motul has been phenomenal for me

SOOOO I've always used full synthetic way before most vehicles started recommending it from the manufacturer. I've ran mobile 1, royal purple, and a few others. When we got our 2007 Mazda 3 all of the records/receipts showed conventional Castrol was used. I've stuck with it to see how it do... I've increased the weight "one step" because we live in a hotter than average climate but we just hit 290k miles with not major issues... my average MPG is 31.x and I typically do 10 over the speed limit (so it could definitely be improved).I change it myself every 5k miles. I think the frequency is more important than the quality with oil. I'd rather have super tech every 3k than mobile 1 every 10k. I think if you stick with any major brand, use a good filter, and change it regularly you'll be fine.

Only used Motul 300V 5w30 or 5w40 since I bought the car new in 2009. Today I'm on 178k kilometers and still on the first chain and chain tensioner. No rattle, no oil consumption or what so ever.

AP1 164k miles using Castro edge high mileage 10w-30. In my experience it does not burn as much oil as Mobil 1

I use Castrol edge because it's rated for high temp engines and BMWs run towards the hotter side.

I’m running Castrol GTX Classic 20w-50. The classic one has the extra zinc, I think they make another GTX that doesn’t.

In my experience it pays to use the right oil and brand is important. I always use Castrol EDGE, but i am in a hot climate and i load up my engine.

I do have slight oil loss but I also track my car several times a year so it's to be expected. Recently switched to 5w-40 motul so we'll see how that does.
