Hi all,
Can anyone confirm if there are synthetic and semi synthetic versions of the Rubia 8900 oil?
I was under impression it's fully synthetic only. But Google seems to show both semi and fully synth articles.
Can someone help me breakdown the 8900 please? I've got access to cheap 10w 30 8900.
I've done some reading regarding the TBN and HTHS. Seem favourable enough. Meets main OEM specs. So must be decent base stock oil?
It's for a passenger car, 3.0 turbo diesel running about double factory power, ~500bhp ish, that gets run hard daily. But short OCI, typically 3-4000 miles. No dpf to worry about.
Redline about 5500rpm. No oil cooler but there's no track abuse or vmax runs so I'm not too concerned about excessive oil temps or oil breaking down prematurely. Generally a nice efficient setup.
8900 is 10w 30. I have been using the 9900 which is the 5w30 version and the ideal weight for this engine. Seems good so far. Engine spotless when I changed timing chains.
Am I right in assuming 10w-30 will be thicker until up to operating temps? So 10w will be ok to use (British climate)?
I read something about 10w oil being same viscosity at 0c as 5w at like -10c or thereabouts. So whilst ambients don't get too cold, maybe 10w-30 won't be ideal where most wear occurs during cold start?
Sorry for the newbie ramblings. Appreciate any input to help. Thank you!
