Hi everyone,

I want to source my own oil for my AM V8V 4.7. People recommend the Castrol 10W60. I found it on Amazon for $120 for 12 liters. I believe my 4.7L takes 10 liters......not sure?

Is Amazon the cheapest?

Is brake fluid Castrol SRF? Any others suitable brands? This is done once every 2 years right?
Amazon is kind of expensive. If it is this bottle, it is $95 each.

You can get two 5L jugs of Motul 8100 X-Power 10W60 for $84 on Amazon.

And Castrol SRF is great, but ultra expensive, and you have to take into account volume... your car needs 1.5L, and those come in 1L bottles, so you'd need two and you'd be wasting a half liter (once you open it, you can't let it sit for too long, so it'd be a waste). I run Motul RBF 600 on my car (and I track it), and you can get that in 0.5L bottles, so you'd need three and it'll work just as well. If you track your car A LOT, go with the SRF... but the RBF 600 is fantastic for street cars that get tracked occasionally. (And it has a higher wet boiling point than the RBF 660, which is why I run 600.)

 

I have good luck at Autozone.

 

I would suggest to stick with Castrol React SRF or whatever the manual says. For my DB9, I noticed a lot of difference with Castrol React SRF and others.

 

IMO: I would use Castrol brand for engine oil, as far as for brake fluid, get German brand DOT4 ( Ate or something similar) fluid, unless you're planning to track it..2 liter should do it. should not be more than $25 each. don't waste your $$$ on brake fluid..

 

Try eBay. I bought the oil to do all if my cars there this year. It is nice having it shipped to your home. Just search for the oil you need then sort it by price lowest.

 

The manual says any Fully Synthetic 5W-50 or 10W-60 oil to specification ACEA A3/B3 is acceptable. There's nothing magic about Castrol.

 

Why would oil sitting in a jug go bad over the course of a year? It's not hygroscopic and it's not unstable. As long as you're not contaminating it in some way, it's perfectly fine to use on the next oil change.

 

I was referring to brake fluid. My DB9 manual says "React Performance DOT 4". Here is link to an excellent article from Rich's site.

Just as with the other comment, you're confusing brake fluid and motor oil. Brake fluid IS hygroscopic, and that's what my entire second paragraph is referring to.
