My Volvo specifies a 0w20 oil that meets RBSO-2AE. The car takes 5.2 liters of oil from empty and manufacturer OCI is 1 year or 18000miles although intend on halving this.
Does anyone have any experience in using thicker oils in the Drive-E engines?
My two concerns are the variable oil pump and the variable timing. What does the oil pump 'vary' on? Is it RPM, load or oil pressure?
I'm a bit of a Fuchs fan, the majority of their oils are really keenly priced and they like their manufacturers approvals which to me mean a lot more than "Meets or Exceeds".
My current fill Fuchs GT1 Pro V 0w20 is £9.87/litre making an oil change £51.32 plus oil filter.
I run Fuchs GT1 XTL 5w40 in the other 7 cars I look after, it's a great 'universal' PCMO. It's an ACEA C3 lube with Dexos2, LL04, 502/505.01, 229.5, 229.31, RN0710 and Porsche A40 thrown in for good measure. It also costs me just £5.13/litre making an oil change just £26.68/litre plus oil filter which is much more reasonable.
RBSO-2AE are mid-saps oil and they all seem to have a HTHS of 2.9 which is very high for a 0w20 oil.
I'm thinking of doing 2x 9000mile/6 month OCI's with the 5w40 and getting an analysis done and seeing what it looks like.
Anyone got any reasons I shouldn't give it a try?
