Engine oil ELF or OEM FORD

On a side note, if anyone really wants to see what their oil change interval should be, just get an actual oil sample analysis done. Per the lab reports, I can get 8k miles on quality synthetics and still have a good safe margin for oil life.

Ford is telling me to change oil at my Focus every year or every 15000km (9300 miles)

5w40 for sure, my engine sounds happier, quieter, more sound than it did when the PO had 5w30 in it. So 5w40 is a given especially since you have a lot of Km on the clock, when it comes to the brand it really doesn't matter especially if you keep the oil change intervals reasonable.

I use Elf Oil and I change mine every 5-7k miles.

I red-line 1st and 2nd gear when merging onto highways from the on-ramp. But then cruise at 100 kmph on the right lane. Gotta have fun when you can! Ensure that **oil** temps are good, not just the coolant.

I currently use ELF Exellium NF, Motul is good too I was tempted to get it....you can also check out ECS Tuning, they sell Lubro Molly now, I think that's gonna be my next choice and I might stick with it. I've used Amsoil for about 20K miles and liked it too. Otherwise, you can't go wrong with Castrol Syntec 5w40 either, I've used it since new all the way till 60K miles.

I used ELF Excellium NF 5W40.

I personnally use Elf and love it, best oil I ever used so far.

Now, I realized that the engine oil the mechanic put on when I got the camshaft replaced in november, is actually meant for cars. The oil is the ELF sporti TXI 10W40.

I have a 98 TDI with 269k and I had an 06 TDI with 131k. I have dumped the unfiltered engine oil after each change into the tanks of both cars since I've had them (Beetle, 98, got at 230,880 miles). They burn fine.
