Engine smoother now! What made the diff???

[Kianbeng]

Hi Guys,

 

I've did quite a bit of things last sat.

 

1) Oil change (standard carrefour cxxxxxe)

2) Oil filter (this time bought original. Last time occasionally also will)

3) Air filter (change every 20 or 30K. Religiously bought no brand ones)

4) Spark plugs. Last time always buy the $2.80 bosch plugs. Now it's the $2.50 autolite plugs

5) Tuned the "slow" idling to a bit faster so that engine don't vibrate that much.

6) Wash engine

 

After servicing, the following day, I realised that when I started the car, the engine sound was a bit quieter. Usually, for the past 4 years (I always listen carefully everytime I start the car one - habit), esp when I start the car in the morning, I'll hear a few seconds of tappet sound....then no more. Now, I completely can't hear it liao when I start the car. So seems to be an improvement.

 

Last time...I remembered when the car was super new....Mazda Motors was using the normal thick engine oil. Always hear the tappety sound for like 10secs when cold start. Then when I started using fully synthetic, Mobil1, Shell Helix, blah....Then I realised that the tappety sound only last for first few 3-5 secs. Btw, the tappet sound very light only. Since 2 years back, I started using cxxxxxe liao.

 

And only after this servicing, I realised the diff. So happy. What do you guys think it could be the prob or servicing that made this difference? Can't be the car wash right? But it's the only significant thing done so far! 4 years of tappet sound leh. now suddenly don't have liao.

 

so happy you know.

no need for poll lah. the only thing that affects the lifters is oil.

1. Feel happy for you for the new found zest in your car.

 

2. Frankly, all that you've mentioned are just very basic servicing that most of us would have done to our cars. However, I'm not really sure what you meant by wash engine?

I would say the above three contributed to smoother running.

I must said engine oil is the main factor

Bro, i think your new engine oil cum new spark plugs contributed to the smooth engine feeling

You've said it yourself already.

 

Sparkplug and engine oil also helps.

tats becos u replaced new engine oil bro

[Kianbeng]

then how come previously when I changed the engine oil I don't feel it? It's not the first time using cxxxxxe. I think this is like 5-6 times liao

[Gary84]

then the spark plugs played a part too..

[Kianbeng]

But the vibration thing....was a recent thing. So adjusting idling maybe only set it to somewhere when new? When new....no vibrations. Maybe idle was high. But when you cold start the car, tappet sounds were heard for a couple of secs...

[Kianbeng]

But last time also got changed engine oil + spark plugs together. But only diff is....this time, I'm using autolite. So cheap plugs....cannot be better than the cheap denso, bosch or ngk plugs right...?

[Kianbeng]

Cannot be lah. I was kinda shocked when I couldn't trace the tappet sound in the morning coz I was so used to it liao.....

 

I'm usually very attentive to such details one leh. coz last time I drove an old car. Valves loose liao....tappets always run. So I know how to tell....

[Kelpie]

Pardon my ignorance, how do they wash your engine bay?
