CPH Posted February 2, 2018 Share Posted February 2, 2018 Thailand is considered heavy duty for the car. Hot all year and lot of dust on the roads. Lots of potholes. Therefore the increased service intervals. Link to comment Share on other sites More sharing options...

Therefore the increased service intervals. In Switzerland I was driving in all conditions, from minus 20°C to plus 40°C. Many mountain roads, not all of them good, dusty quite often, on building sites, long distance and town driving. Service interval 30 000Km Link to comment Share on other sites More sharing options...

This exceeds recommendations for synthetic oil. Link to comment Share on other sites More sharing options...

Some oils such as the annual Mobil 1 synthetic are good for 20k miles. But in Thailand at least, they are not used by the dealers. I assume because of the cost. I don't know about cars in Europe though. Perhaps dealers there use top spec oil in some makes. Link to comment Share on other sites More sharing options...

I have heard the rumour oil degrades faster in hot countries but have not seen any oil manufacturing companies confirm it so could be an old wives tale...

CPH Posted February 4, 2018 Share Posted February 4, 2018 Here is something from Valvoline on severe (heavy) driving conditions which require shorter maintenance intervals: And you might be surprised at what severe driving can include: Frequent idling for long periods of time Stop-and-go driving in heavy traffic Sustained highway driving in hot temperatures Sustained highway driving in freezing temperatures Short trips (less than 5 miles) in normal temperatures Long-distance trips at speeds of 50mph or less Regular trips along steep hills or mountains Any trips along dusty, muddy, salted, sanded, or gravel roads Any trips that involve towing a trailer or a camper Any trips that involve transporting items via roof rack or car-top carrier Link to comment Share on other sites More sharing options...

fredob43 Posted February 4, 2018 Share Posted February 4, 2018 Toyota say in Their hand book if you do lot's of high speed? runs here, you should change your oil and filter at 5,000km regardless of what oil you use. That's on a diesel lump. But then again what do Toyota know. Link to comment Share on other sites More sharing options...
canthai55 Posted February 4, 2018 Share Posted February 4, 2018 Cummins says X15 Efficiency Series and X15 Performance Series engine owners can extend their oil drain intervals up to 80,000 miles using the free Cummins OilGuard program, which uses engine performance data and oil analysis to safely optimize oil drain intervals. http://www.truckinginfo.com/channel/maintenance/news/story/2017/02/cummins-extends-oil-drain-intervals-up-to-80-000-miles.aspx And no - they do not specify full syn - for all those know-nothings who swear you need it. “CK-4 engine oils will be a direct replacement for the engine oils fleets are using now,” says Dan Arcy, global OEM technical manager for Shell Lubricants. “You’ll be able to buy the same viscosity grades and oil types [conventional, full synthetic, synthetic blend] you’re using now, and they’ll be ‘backwards compatible’ to all current vehicles. http://www.fleetequipmentmag.com/demistifying-new-engine-oil-categories-compatibility-ck4-fa4/ Link to comment Share on other sites More sharing options...
