I am wondering for summer I should switch to 5w20 instead of 0w20. I think that will also help to reduce the lifter noise...thoughts???
Let me know how does that go0w20 or 5w30 are acceptable to use per the manual. I don't see a point in using 5w20.
I'm giving 5w30 a try for this summer.
correct me if i*m wrong, but both of those have the same viscosity when hot.
Unless your car is consuming oil, i don*t see a need for a higher weight.

I've had good reports with Castrol Edge 0w20. But I started using Pennzoil Platinum 5w30. It's been a while since I sent in any samples for reports (do have the samples though), so will have to see how the Pennzoil is doing.Mine also was getting noisy with 0w-20. Went to Idemitsu 5w-30 and it's a lot quieter and the engine likes it. It even feels like the engine 'pulls ' better. The 2 prior changes were Castrol Edge 0w-20 which turned almost black at 2500-3000 miles and seemed like it thinned out. The Idemitsu is looking better at 2000 miles so far. I don't know what it is with Castrol oils, but I've tried them occasionally throughout the years and never stayed with them even though they are supposed to be good oils.
No, if you really want to reduce the valve lifter noise, you should use 5W-30 oil. Switching to 5W-20 from 0W-20 won’t make any difference for normal engine running temperature.I am wondering for summer I should switch to 5w20 instead of 0w20.

Running 0W-30 or 5W-30 actually is also recommended for SkyActiv-G 2.5L by Mazda worldwide other than North America.OK, so I had an oil change today done at a new (to me) dealership, and I requested 0W30 instead of 0W20.
They discussed it briefly, and said that it wasn't a problem. I've always though that this 0W20 was a little thin, although I have nothing to back that statement up with.
Anyway, given that the rest of the Mazda world uses 5W30 in this engine, I wanted to try this grade (0w30) to see if it makes any difference.
Hard to tell on the way home, but it seemed to me the car sounded and felt a little happier.
It's probably just my imagination, so I'll see how it runs and feels this summer.
Yes, I did agree with GJ-Molester’s point at the time that by using the 5W-30 our SkyActiv-G 2.5L will be quieter (and may be even better off with 5W-30).I still remember GJ-Molester a few years ago on here, and his rants about oil grades and how he swore that his car was better off with 5W30 in it.
I may try that next.
What year/model do you have? Where are you located? Current 2.5s use 5W30 oil…haven’t seen 5W20….Somehow I got 5W20 which is not a recommended oil. Would not think I would get a 'Close enough' solution from a dealership. Have not made a final decision, but thinking I will bring it to an independent shop for the next service visit.
5w30 is at least in spec with Mazda recommendations. His problem was that he was recommending even thicker oil like 5w40 which is not.Yes, I did agree with GJ-Molester’s point at the time that by using the 5W-30 our SkyActiv-G 2.5L will be quieter (and may be even better off with 5W-30).
