Hi sifus,
Just want to ask here... What are the suitable engine oils for blacktop. The reason is because I plan to change my car's oil grade. I have been using 10W40 all along. Planning to change to 0W30, 5W30 or 10W30. The reason is because when I was using 4AFE, I realise that the "30" series does make the engine feel lighter and fuel economy improved. However, I'm not sure if this can be used on blacktop since it is high revving.
1. Will it provide enough protection at high load, high rev? I do not blast all the time but occasionally just for fun and overtaking. Mainly city drive.
2. Will it fail to protect the vvt pulley and solenoid? I have heard people say that the blacktop vvt controller will fail if we use the wrong type of engine oil. Don't know its true or just myth.
Thank you for your input.
