[QUOTE="KiNaKa, post: 204029, member: 184"] E30M20b25 is my ride. Previously i'm using AMOIL 10W-40, [I]PETRONAS Syntium 3000 0W/30.[/I] Now I'm using Shell Helix Ultra 15W-50. Almost the same & so far so good for all of this oil, but the shell seems having a good oil quality after the engine running for 10000KM. This is what i noticed after testing the oil quality by the oil sensor. Old model engine Thicker oil grade reduce the wear & teppet sound. It prevent oil consumption cause by the old piston ring, gasket too. *fully synthetic oil are recommend if the old engine has been rebuild. Late model engine Thinner oil grade allow the smooth flowing in the hydralic teppets & mechanism such as vanos/camshaft adjuster. Smaller gap between components allow smooth flowing & better acceleration (engine feel lighter). higher oil viscocity allow the engine oil stand up to higher temperture before it malfunction. so its much suitable for those high performance engine. My 2cents... [/QUOTE]
