Castrol magnatec, 10w40 semi!95 HSE 4.6
The one and only previous owner used synthetic, but in the loads of service history it only states that the oil has been repaced with synthetic not the make or grade,
Any ideas what I should use?

Hi
I have always used a semi synthetic oil in my 2000 4.6 which I change every 4 to 5000 miles. I recently had it serviced by a independent and they put Castrol Classic XL in which is a 20-50 grade mineral oil for modern( 60's to late 70's)classics. This has shown a improvement in oil consumption and as I change the oil at these sort of miles the detergent effect of synthetic or semi synthetic would not seem to matter. The guy said thatwas in his opinion Castrol XL was the ideal lubricant for a engine thats been around since the 60's
