I guess the culprit is the thicker oil which i have used i.e. 10W40, shell helix HX-7, car vibarting a bit more and as far as i can understand due to thicker oil initial pick is not as good as it should be. Before today, i didn't know much about oil classification, but this site www.bobistheoilguy.com was really helpful. After gaining some information over the internet, i have come to know, 10W40 is a thicker oil. Thicker oil is more suitable to older cars where oil level goes down during driving. The shopkeeper didn't inform me this and i was stupid enough to buy it blindly I guess the 10W30 or 5w20 could be good for vtec. Lighter oil means less work for engine, hence a quieter engine. Now this thicker oil in my car needs to be flushed.
If you guys have any experience which oil is the best for vtec-cvt, please do share.
I have CNG in my ride but hardly used it after 36k, and in 36k only 60% is on CNG. Also I am thinking to get rid of CNG, very likely that it is going to be uninstalled.
iridium plugs were installed at 35k and now car is at 46k.
btw, which plugs you have in your car ? how you feel that response is improved?
Also here is lengthy but very good article about vtec steermatic (Vtec/Jazz). Tell you pros & cons of steermatic ride.
