Relief valve is in the same spec range.

 

I definitely plan on that!

The AM is a well designed oil filter, designed for street use.
When i was racing an open wheel formula car i would use a race type oil filter like the Ford racing, different design parameters and trade offs, less HP loss, but those engines get refreshed once or twice a season (maybe 500 miles or less) and the oil filters are replaced every other race on average.

 

Just wondering if anyone has performed an oil change by inserting a hose down the dipstick tube and pumping the oil out through the hose?. This method is the only one available for my XJ V-6 so I have the equipment and it sure is easier. The primary concern is whether the hose lands at or near the lowest point in the pan. I was going to monitor the amount removed and decide if it was close enough to 12 quarts to conclude the pan was drained, but maybe someone else has already tried this and can report on the result?

 

All i can offer up is on my V12 I overfilled the engine and tried to remove the excess oil via the dipstick tube with no luck at all.
I tried 3 different sizes of tubing but it seemed to get blocked just before entering the oil pan, so all I was pumping was air.

 

Curious, how did you end up removing the excess oil capacity?

 

I still had the belly pan off so up on the quickjacks and via the drain plug.
I reused the new drain plug, no issues several hundreds of miles later.

 

Hi Guys,I’ve been an Amsoil Preferred Customer for years and use their stuff in just about anything in my garage with a piston. When I picked up my 2005 DB9 last year, I reached out to Amsoil tech support to see what oil they’d recommend. Their reply was interesting—they said they didn’t have specific data for this car in their system, so no official viscosity listed. But the specs suggested their 5W-40 European Car Formula Classic ESP (EFM) would meet the requirements… they just couldn’t say what viscosity Aston prefers.
I figured the full SAP version was right, but I was stuck between 0W-40 and 5W-40. In the end, I went with the 5W-40 I already had, and it’s been great. Of course, being a good synthetic, it also finds its way past my gaskets and oils up the underside of the car. One day, I’ll finally fix that timing cover leak.

 

so mobil 1 is for short interval service, 5k miles max, you see? amsoil is way better or ?i just got some mobil 1 again....

 

Mobil engineer thought it was interesting in the Aston's owner manual, they refer to specifications that are associated with diesel cars in addition to gas engines.
