Please I need help. My car started smoking after changing from mineral to synthetic oil.. should I be worried?
I would probably increase the viscosity of the oil if switching to a synthetic on a car of that age that was previously using conventional oil. But since you didn't provide any details on what oil you are currently using, it is hard to say for sure.Thanks all.. response where helpful. I spoke with an auto mechanic who said it's because of the synthetic oil I used but I should watch it because the smoke will disappear as the car is getting acclamatized to the synthetic oil. Lately the smoking i think has reduced but I'm still observing it.
The idling is perfect too and calm. Car is 04 toyota camry.
Thanks again all, you guys are awesome.
A car that switches to synthetic after the first oil change will not likely have any problems with oil burning, or at least not because of using synthetic.My 2005 Camry V6 with 1mzfe engine has been using Synthetic 5w30 Amsoil on the first 8 years and only a yearly change, then it was too expensive and it was very difficult to buy because the retail store no longer carry. I switch to Pennzoil Ultra and then Pennzoil Ultra Platinum also a yearly drain but I always use Fram Ultra synthetic oil filter. Car never smoke on start up, oil leak or oil consumption for an 15 years old car. Now it was around 370,000km or 230,000 miles on it and engine is pretty smooth and reliable.
I would encourage you to do some additional reading on oil film strength. The differences between modern conventional oil and synthetics for the situations you describe are minimal.synthetic oil give an extra protection during winter cold start and the scorching heat from the summer.
How does that person explain why Toyota, Honda, and virtually all luxury car manufactures require synthetic motor oil in their new vehicles? It doesn't explain it, and that is why that person has no idea what he is talking about.On another forum I frequent someone recently said this, "Synthetic oils were designed for high temperature use in jet engines, they have really no part in motoring, unless you want to make money." And that's also consistent with the observation about turbocharged/supercharged engines as well, which do involve higher temperatures.
Film strength? There are no 0W-XX conventional motor oils, bud. A 0W-XX motor oil will have better cold weather starting capability than a 5W-XX motor oil.I would encourage you to do some additional reading on oil film strength.
