I have read a lot of previous posts about blending engine oils. All I have read pertains to climates that go thru cold winter seasons, while here in Scottsdale, AZ, the lowest temps go no lower than 30F maybe a handful of days during our winter months, and summer can see 117F at times. Keep in mind that these landmark temps on either end are only registered for a few hours during daylight for highs and eves for lows. My question is a bit different than most. I am not trying to pretend to be an oil engineer with the idea of mixing different weights for the sake of trying it out. I just bought a different car, a 2012 Hyundai Genesis R-Spec with a 429hp V-8 for power. It has not used a drop in 3000 miles. The maintenance manual lists a small variety of suggested weight oils based on temperature. It calls for 5w20 or 5w30...OR 10w30 if temps are above 0F. My temps will never be close to 0F, so I think the 10w30 is the way to go. I know the prev owner put 5w20 in it just before my purchase and is full syn. The valve train looks spotless with the filler cap off. It has 82K miles. That being said, the next oil change is coming up and I have 3.5 quarts of 5w30 Pennzoil Platinum High Mileage Full Syn on the shelf left over. The capacity on Genesis is 7 1/8 quarts. I want to use the remaining 3.5 qts of 5w30, then add another 3.5qts of 10w30. Or do you recommend to just go with 5w30 all in for the upcoming change and switch to the 10w30 the following time?
I am using this brand because of its low evap rates which is a consideration with these GDI engines. Also thinking about adding one or two catch cans. I am a past AMSOIL fan, using their extended use for up to 22K miles in my BMWs and never had a problem with burning oil or engine problems running them up to 300k miles. But at nearly $10/qt, and these newer engines, I am not so sure if I want to continue that process. Th economy makes a ton of sense with long durations, so the cost per quart really is not a factor when saving money and time. Anyway, feel free to comment on my original question. Thanks.
