and the bella has turned into the car version of Ollie Reed.
Firstly my mistake, not Selenia (seem to have that on the brain lately) but was AGIP oil that was used in my car. Why I thought Selenia, I don't know. Berk!Shouldn't make any difference.
It is the same spec, same viscosity and also a semi synthetic.
Are you 100% sure it was the 10w-40 version?
Nah me and Thompatruck did the service and used up a 5L drum of Mobil.Was the Agip the 10w-60 version?
That could explain it, but I will stand by my belief that 10w-60 is too thick for a TS (Or V6)engine.
It is possible that they didn't fill it right up at the service.
It's optimum operating temperature is much higher than a 10w-40, therefore it will never reach its operating temperature in normal use.How is it too thick? I only run my TS on 10w60 and never had any problems plus does not drink anywhere near the amount it did when it ran on 10w40 plus car runs much better.
They will mix fine, but it would be better to change the lot.If you intend to use a 5w40 over a 10w40 in the future, can the two mix as a one off to get things rolling or would a oil drop and refresh with 5w40 be better?
CheersThey will mix fine, but it would be better to change the lot.
The trouble with a "Rolling change" is that when you add new oil it becomes the same age as the oil that is in there due to the number of deposits and other combustion by-products in the old oil.
