If your engine doesn't burn oil, using a quart of this during a 5 Qt change shouldn't make it too thin. Otherwise you could mix it 50/50 with 5W-40 come out with something +/- 5W-30.

Castol Edge Titanium 5w-30
Another way to put it, now that the Castrol Syntec 0W-30 is no more, what oil should I use? (I know, kind of a stupid questions but...)

I believe the Castrol Syntec 0W-30 is discontinued. At least I can't find it anymore. I ended up using Castol Edge Titanium 5w-30 the last time I changed my oil. Anyone have any information on this?

I wouldn't hesitate to change to Mobil 1 0W-40, Pennzoil Plat 5W-30, Edge 10W-30, GTX and Pennzoil yellow bottle 5W-30 with short oil change intervals.

autozone still has castrol 0w30. i checked the spec for mobil 0w40 but to me, castrol 0w30 has better, higher flash point and boiling point(?), spec than mobil 0w40. i don't see how that's possible cause mobil 0w40 is "suppose" to be thicker.
i want to go thicker than castrol 0w30 that has higher flash point that 0w30. Anyone know which one?

I have been reading thru the posts and i dont see anyone using 15w40s. It is possible i overlooked it. Has anyone done this during the summer and if so what was the results. I have a 3.5L that just had the tensioners replaced and the guy recommended that i run the 15w40 in the summer and switch to 5w40 in the winter. His explanation was that it would coat the pads better and prevent some wear. I have been reading on here and now im questioning him because the tensioners are oil pressure driven so if the oil is thicker then the pressure is higher therefor increasing wear. Please dont beat me up on this. I dont know much about these engines as it is the first one i have ever owned. I know the guy i but it from used regular pennzoil for 4000 mile changes. It now has 103K miles on it and just had the tensioners and cats replaced. It was costly and i would like to try to avoid it happening again if possible. Also feel free to PM me so it dont muddy up this post.

i switched over to Castrol 10W40 this time from castrol 0w30.
The oil pressure at idle for both of them are similar to each other.
What's weird about 10w40 is that when going around 70 mph, oil pressure reads 80 psi. 0w30 read around 67 psi last time.
this normal?

hopefully you are mixing in some ester oil or you will start hearing some insane amount of valve train noise... nissan ester oil is positivly charged so it "clings" to metal to protect during cold starts

If you buy mobile1 oil filter $12.99
then the first 5 quarts are ~$4 something

6 quarts of 0-30w "Eurpoean Formula" and a m1 filter for $70.00, really after tax i got a even number (Autozone)
Is there another store that might carry a 5qt bottle or something? $8.49 per qt sucks.... maybe i have been to spoiled with buying a 5qt of m1 5-30 for $22 at wallyworld?

On the east coast, GC should be on sale next month at Autozone or Pepboys. My local Pep Boys has GC, but it goes really fast when it's on sale. I don't know for sure but it usually alternates every other month or however long the stores put things for sale on their flyers. Don't worry, if you can't wait Mobil1 is currently on sale and 0W-40 is readily available. You also have 1gal containers of T6 Rotella 5W-40 for the guys running test pipes or turbos and that's always available at Walmart. All you have to do is buy two and you have extra refill for our thirsty VQ motors lol.
