Hi All,
Apologies, I know this topic has been discussed widely. I have searched the forums and Google but still require clarification as some people are providing conflicting information.
I have a 2006 IS250 and I need oil.
Castrol Oil recommendation tool states: Magnatec Stop-Start 5W-30 A5 and Magnatec Stop-Start 5W-30 C3
Opie Oils recommendation tool states: Magnatec Stop-Start 5W-30 C3
My forum searches bring back a range of recommendations because some people say you need Decos2 compliant oil (C3) whereas others recommend the A5.
The Lexus manual which I found online (http://drivers.lexus.com/t3Portal/document/om-s/OM53508U/pdf/OM53508U.pdf) states "SAE 5W-30 is the best choice for good fuel economy and good starting in cold weather. If SAE 5W-30 is not available, SAE 10W-30 may be used. However, it should be replaced with SAE 5W- 30 at the next oil change".
It doesn't tell me whether I need A5 or C3. Can anyone assist me in deciding between Magnatec Stop-Start 5W-30 A5 and Magnatec Stop-Start 5W-30 C3.
Thanks!
