I’ve used Castrol and Castrol High Mileage on my Mk6. At just over 143K miles, I’ve had no engine issues at all.
Been running Castrol in my VWs for 20 years. Never had any issues.
Castrol euro has been good to me for the last 120k miles.
em troca do óleo eu sempre usei 5w30 da Castrol, ate agora com 227.000kms com o mesmo motor só misturei 2 oub3 vezes no deposito da gasolina. Sempre foi o meu carro e nunca me deixou na estrada
I'm seeing a lot of strife around these comment parts on this post; but I will tell you this: If previous owner used only conventional, you best use conventional for the sake of the rubber seals on the block. If you want to eventually run synthetic after your first rebuild, be my guest, although I would recommend going the sohn adapter at that point, just for extra insurance that what you're doing is good for the engine.
I don't know where you're located, but I've personally ran Castrol GTX oil in all my cars up until now; the only thing is, it's harder and harder to find conventional oil that is of thinner grades. Which isn't a bad thing, because the RX8 needs thicker oil than what's on the oil cap anyway! 5w-30 should be your minimum thickness, but really, it's recommended you go thicker, to like 10w-40 for year-round, and 20w-50 for track days or extremely hot climates. There's this shell oil for diesel that's rated at 15w-40 that I was going to potentially pick up and start using. Yeah your fuel economy is gonna drop a tad, but you're really doing it for the sake of your bearings.
P.S. get an oil catch can that vents to atmosphere if legal in your area. It will save you heaps of headaches down the road ????
Castrol magnetic 5w30 best utk jimat petrol
I switched to Castrol Edge 5w40, and what a difference! It loves it. We didn’t lose any fuel mileage, just as Pepe. but much much smoother.
Car idles smoother with Castrol it seems.
For example my previous BMW engine was very noisy with mobile 1, and quiet with castrol
Today I changed my engine oil to castrol power1 Cruise 15w-50 with TVS engine oil additive. Post that my engine starts to vibrate at bit early rpm & getting hot more quickly & frequently.
