VW now mandates synthetic for their Turbo engines to prevent sludge build up. (0W-40)Petroleum motor oils are prone to boil or vapor within the normal operating temperature of the engine. This is commonly referred to as breakdown. Once the oil begins to breakdown it usually results in oxidization creating hardened oil deposits in your engines components and sludge. Synthetics by contrast, are able to withstand greater heat temperatures resulting in greater protection against breakdown.
Heat is a major enemy of any engine. Heat produces friction and friction produces wear and wear reduces the life of your engine. The uniformly smooth structure of synthetic motor oil, free of the components found in conventional petroleum motor oil provides superior protection against heat, friction, and wear on your engine. Simply put, synthetic motor outperforms conventional motor oil when it comes to protecting your engine against heat.
Provides superior start-up protection
Petroleum motor oils contain waxes and parrafins which can thicken when exposed to cold temperatures. Once the petroleum oil is cold, it makes it difficult for the oil to get from the oil pan to the moving parts of your engine during cold-weather start-ups. Meanwhile, until the oil heats up and is fluid enough to circulate through your engine, damage is occurring to your engine which over time can reduce the life of your engine. Synthetic motor oil on the other hand, does not contain these waxes and has fluidity properties which allow it to get into your moving parts almost immediately providing greater protection for your engine.
In terms of engine longevity in harsh environments, synthetic wins hands down. Use Mobil 1 which you can buy from WalMart for less than US$5 per quart, and run extended oil changes with filter changes at the regular interval.rjhoffmann said:I was informed by the dealer that I could use either synthetic or regular oil in my new RAV4, V6 AWD. I was wondering if there are any ideas about whether the synthetic oil is better for the life of the engine?
here one link. Just google "synthetic oil myths" and you get several pages of links..OCInsomniac said:Somebody help me here with the link I've seen several times :idea:
As it looks like the V6 uses a cartridge filter and not a spin on I would be surprised if you can change it without have oil drain out.BarnyFife said:Does anyone know if you can replace the V6 oil filter without losing the oil, the way it hangs down so low near the same level as the oil pan, I wonder.
I had to run M1 0W40 Artic weight during winter in Alaska or my Integra would start like it had cement in the oil pan(I didnt use my block heater, no plug ins at my apt). I changed it out as soon as it started getting above 40 deg as it was too thin for normal temps.r said:Just for fun, put your favorite dinosaur oil and some Mobil 1 into some small clear jars and put them in you freezer overnight. Once you see them the next day, you wonâ€™t go back.
