Dear Pakwheel Members,
In the past i was using Delo Gold 15w40 and Tyota GL-4 gear oil. I am not satisfied with the quality right now in Pakistan. My ce100 corolla engine was rebuilt @ 200,000 km. Now its 50,000km after engine overhauling. Last year i switched to Valvoline Premium CI-4 15W40 and maximum i change the engine oil @ 2500km (with Alco oil and fuel filter) and transmission oil @ 10,000km.
There is one thing i note that Delo Gold 15w40 and Toyota 75W90 are thicker than Valvoline and Toyota.
Is this oil suits to engine and transmission.
There is no engine oil leakage and no oil reduces uptill now. Kindly suggest should i continue these oils.
When i use delo gold my diesel fuel consumption increases and by using valvoline engine feels smoother and millage increases.<o:p></o:p>
