tomicacars September 29, 2018 Share September 29, 2018 Saw on Meta facebook that they are increasing price again. They have some promotion $19.90 for next 2 weeks in Giant Tampines, Vivo and Turf. Anybody saw it in these places? ↡ Advertisement Link to post Share on other sites More sharing options...
Terratoss 1st Gear October 14, 2018 Share October 14, 2018 Two oil may have the same viscosity on the bottle, but yet can have different viscosity when in use. Lower viscosity usually improves FC unless the engine doesn't call for it. If want more friction modifiers, use Caltex with Techron Clean & Glide Technology. previously i was on shell 5w40, now 5w30 but doesn't seem to have any noticeable FC improvement.

Kklee 6th Gear October 15, 2018 Share October 15, 2018 The shell im talking about is shell helix ultra 5w30 & 40. Viscosity at 100 degrees-Celsius, the difference between Shell Helix Ultra 5w40 and 5w30 is 0.9. Shell Helix Ultra 5w40 is at the lower range of the w40 where Shell Helix Ultra 5w30 is on the higher range of the w30. The difference between Shell Helix Ultra 5w40 and Pennzoil Ultra Platinum 5w30 is 2.8. For comparison, difference Meta & Shell 5w40 is 2.9 or Meta & Shell 5w30 is 3.19. IMHO, if between Shell 5w40 and Shell 5w30 is not significant, try an even lower viscosity EO like Pennzoil 5w30 or Motul 5w30. If it is to resolve a FC issue, then perhaps a dose of fuel system cleaner like Caltex Techron Concentrate or Redline SI-1. If still the same, look at other components like throttle body.

Kklee 6th Gear October 16, 2018 Share October 16, 2018 Engine is a critical component of the car and it is very expensive to change. I won't recommend to go below w30 if you intend to keep your car beyond 5 years. There are cars that the manufacturer recommends to use w20 or w30 or w40, etc I would think that there are variety of reasons. It could be that some engine design needs a lower viscosity to prevent the build up of heat. w30 is a range of viscosity. - some closer to w20 and some closer to w40.

I won't recommend to go below w30 if you intend to keep your car beyond 5 years. Not true at all. If the owner manual state 0W-20, pls use it. What u need is a top grade full syn engine oil and change the oil at scheduled intervals. Pls do not subscribe to those old myth that the thicker the viscosity, the better is the oil. Technology has improved significantly for the past 10-15 yrs while these myth stuck to where they are. Link to post Share on other sites More sharing options...

Thks for yr detail reply!

Kklee 6th Gear October 16, 2018 Share October 16, 2018 (edited) SAE 20 engine oil does not offer the same level of protection as SAE 30 when the engine oil is hot. It is better to be safe than sorry in Singapore where the climate is hot and cars are very expensive. Reference to what you had indicated above (underlined) IMHO. The w30 in relation to ambient temperature ranges in published charts max at either 30 or 35 degrees. The extreme max temperature in SG based on historical data throughout the year is 34 degrees and above. Using w30 will be in this upper limit to the max max temperature. The w40 in relation to ambient temperature ranges in published charts max at about 40 degrees. Using w40 will be a bit further from the upper limit to the max temperature. Safer - w40.
