Guys how much engine oil exactly your tibs need to be full of oil. I put in mine 4.3 liters of oil and it shows nearly at the full mark on the oil stick, just slightly below max level. I know tiburons are supposed to need 4.5 liters oil filter included. What are your observations on the quantity needed? Cheers
The manual of the Tiburons are rotten and they say lot of crappy things right there.
I heard lot of people running thinner oil that the manual specifications, but, if you want to run 5W40, it's your right
Below 0°, 0w30 is the best, and the 40 grade when hot is not necessary as i said before.
You will never break down the lubrification film because you switch between 40 to 30 when hot, and of course u will do better mpg than ever and have a smooth engine.
Sometimes, some are using 0w20, which is not on the manual, and have not broken there car
(and have a heavy foot trust me)
The lifters can be noisy, but slightly, the cams also.
For example, mine is doing a weird thing but it's normal, i can hear when i turn it on by cold climate the oil suction in the oil pan that gurgle like bubbles, and it's normal because the pan has been designed like this.
The injectors are noisy passed 100k miles, sometimes before, i never heard a tiburon quiet as a prius, it's a combustion engine, not a electric engine.
I have a tip for you : Fit a CAI and an Exhaust
