Do I need to drain coolant from engine block?
For many cars, it may never be necessary to flush the engine block – it’s only vehicles that aren’t driven for an extended period or go a long time without oil changes that might need a full flush out. The procedure can be quite complex, and for that reason it’s best done by a professional.

What’s the difference between 15W-40 and 10W 30?
Since 10W-30 is thinner than 15W-40, its film strength can be weaker and it can be more prone to oxidation. Therefore, high quality additives are needed to compensate for those weaknesses in order for 10W-30 to protect as well and last as long as 15W-40.
What is 15w40 oil used for?
What is the best 15W-40 oil to use? If you need a 15W-40 diesel oil, Castrol® GTX® Diesel helps extend engine life, protecting against the wear and tear of severe weather, rough roads and heavy tows.
What’s the difference between 10W-40 and 15W-40 oil?
A 10W40 oil will be thicker in the cold than 15W40 oil, but they will have the same viscosities at higher temperatures. The winter viscosity number dictates cold-start performance. A lower number indicates that the cold oil will be thinner, hence applying less static friction on the engine, and less drag.
Can I use 15w-40 instead of 5w30?
5w30 flows better than 15w40. 5w30 provides best cold start properties. Using 15w40 instead of 5w30 will increase your fuel consumption because of more load on your engine’s crank. No, head gaskets have nothing to do with the oil.
What happens if I put 10w40 instead of 10W30?
This is the reason your location is so important in selecting which oil to use. Between a 10W-30 and 10W-40, 10W30 motor oil would run smoother in colder climates while a 10W40 would be more effective in preventing engine wear and tear in warmer temperatures.
What oil is thicker 5w40 or 10w40?
10w40 is thicker than 5w40, ONLY when cold. At operating temperature it is exactly the same. Multi-viscosity oils with a lower W number are specifically designed to flow better, and thus lubricate better, at very low temperatures. There is no need to use a 5w-40 if the vehicle only requires 10w-40.
