good morning. car is a 99 honda civic vtec. it is due for an oil change. it uses honda's (casa) LEV SL 10W30 oil for its engine. i want to use non-casa oil na fully synthetic. driving style is easy driving lang...

what engine oil (fully synthetic) would you recommend i use as substitiute? by the way, im thinking of shell helix plus (blue)...would it be a compatible substitute for SL 10W30? what should i look for (details)when i buy a compatible oil? TIA
