Speaking from a chemical standpoint, synthetic oil is superior in every way. Brands are almost identical except for the additives in the oil.
The 5S-FE and the V-6 1MZ-FE both had some limited oil problems (do a google search with 'toyota oil sludge' and you can see the results). The oil draniage in the head is not great to begin with and the 15 degree slant to these motors may contribute. With the oil in the head overheating, conventional oil breaks down much sooner due to the impurities in conventional oil (I know I sound like a commercial and no, I don't work for an oil company). I have also read a research paper that was conducted on new york taxis a while back where the cabs used synthetic oil. The filters were changed at the regular intervals, however the oil was not changed for more than 50k miles! The engines were no worse of than one using conventional oil with regular changes. Synthetic oil does not break down, it just gets dirty. Synthetic oil will help your car live longer. |
