Oh No, an Oil question
All this x66 demystifying got me thinking about how chemicals combine in my engine, specifically in the oil.
One of the little things I do is vary my oil viscosity with the seasons. In the winter, I use a 5-30 or 10-30 multiweight oil. In the summer I'll go with a 10-40 or 20-50 weight. Since I buy the Castrol Syntec which is on sale and stocked, I end up with quarts of all of these weights.
Up until the x66 debate, I never thought twice about topping up with whichever quart I had handy. So my oil is "blended" with regard to weights, not brand. In fact, I like making what I call Syntec blend plus, thats 4qts of full Syntec and 4.5 quarts of Syntec blend.
Does anyone think that is harmful and something I best avoid?
