QUOTE(themanf2003 @ Jan 27 2019, 05:30 PM) Can any one guide me in selecting between 5w30 and 10w40 (both fully synthetic for my car, hyundai sonata 2011 ? Which one is more suitable . I have attached a file from my car guide book. Thanks in advance ! According to manual both is fine. Personally I would go for Xw40 for better protection instead of 30 which might give you better performance (feels slightly lighter on acceleration) and may give slightly better fuel consumption.I used to have similar car to yours with 250kkm (optima), had been using Xw40 on it |

For your reading pleasure
5W30 vs 5W40: Determining Which Motor Oil Is Right For Your Car https://www.zoniv.com/5w30-vs-5w40/ << To keep your motor up and running at all times, you should stick to the mechanic’s or manufacturer’s recommendations regarding motor oil. Thinner motor oil flows more smoothly and quickly when the engine is cold, which is why you should not use anything less than 5W-30 in the summer. >> |

To buy or not to buy from local supermarket?!
I hope this would throw some light to the discussion... https://www.freemalaysiatoday.com/category/...o-much-cheaper/ << Well, our research with the industry reveals this – Tesco as a large supermarket chain buys this lubricant in bulk and ships it into Malaysia and so they are able to sell at a very low margin. >> and further reading here as well https://www.dsf.my/2019/04/shell-hx8-price-...-cheap-pricing/ This post has been edited by VeeJay: Nov 28 2019, 11:58 PM |

QUOTE(GamersFamilia @ Feb 19 2025, 08:29 AM) My 22 years old camry acv30 2.0e currently using sae 10w40 fully , been thinking to use sae 15w40 semi or fully 10W or 15W is immaterial for our climate. I would keep it at 40 if you had been using it for a long time. but no harm trying 30 and see how's the performance.So which is better If with 30, the oil consumption is higer and feel rougher, then better to use 40. My car is 15yrs old but mileage is lower, so i have moved from 40 to 30, and feels better. |

QUOTE(Quazacolt @ Jul 13 2025, 02:46 PM) Molybdenum is very popular these days because it's one those additives that doesn't have any obvious detrimental issues. As for Bardhal, C60, it uses MoDTC but coupled with polysulphide complex, as the other layer. Am I correct it the presumption?The only problem is that they aren't like zinc or phosphorus that's able to cling to metal surfaces. Hence their benefits are also very limited. Another "issue" is how there's differences in MoS2 similarly to base oil https://bobistheoilguy.com/forums/threads/w...ar-moly.314523/ I'm not sure if there's any tests or analysis that can determine or differentiate the various MoS2 types. (Base oil you can) The insolubles are negligible and it's apart of my previous Q&A and recent Q&A/notes Regardless, you can also refer to https://www.blackstone-labs.com/all-about-insolubles/ Basically, the MoS2 are smaller microns than the test, as well as oil filter. (Otherwise they are all caught by the filter and just clog it up) I've got enough data of TBN so didn't pay extra for it But through experience and also my previous report, no it doesn't affect TBN Quazacolt liked this post
