Car is doing really well on the Evo/Redline mix. Just seems really happy in general.
Less blow-by but it smells stronger. Not sure what that could signify...

huh?Hi PumpkinKing - Noticed you were looking into motor oil brands for your Hyundai Veloster. Did you decide on a specific brand yet? We wanted to offer you the opportunity to participate in the Pennzoil Used Oil Analysis program. Through the program, you'll receive a kit with a sample of Pennzoil Synthetics and UOA testing supplies. We're working with independent lab, Blackstone, to provide participants with lab results as well. If you're interested, please send us a private message, so we can fill you in on additional details. - The Pennzoil Team
5w40 is the best for a large range of ambient temperatures. Here since the temperature is high we have to use 5w30 or higher, since 5w20 cannot protect the engine at our temp.Since were just bs'ing about earl, i always use the Pennzoil Platinum goodness w a Wix XP Filter. Now ive got this Moly Tec, i think - they make all the good additives but its was for my VW TDI days so therefore, diesel. What do you guys think of pushing this 5w-40 through a GDI - just curious?
Tell that to the people who ejected pistons and rods out of their block. That doesn't happen from simple spark knock nor basic pre-ignition directly, but either can trigger LSPI events. Catastrophic failure (block windowing) happens due to super/mega knocking which is caused by LSPI events. Do some research. Several auto manufacturers, oil/fuel companies, universities and research organizations have published many, many LSPI articles on SAE. It doesn't matter how strong your pistons and rods are. If it happens, the weakest components will break first.Lspi..bahhh.. We never had LSPI issues on this car.. We had shit internals from Hyundai. If im not mistaken Lspi was a marketing pitch for a leading brand of oil...
Right, thanks it's been a while since I've had a car nice enough to warrant remembering that! I was more curious how much the climate would affect the heat sheering of the oil down to a thinner viscosity as I think that was the reason for the TSB switch to 5w-40. I assume there's going to be some sheering even in a moderate/cool climate, so the interval of changes is in the end probably more important than 30 vs. 40 (I'm pretty sure I read that on this or some other thread about oil already, but it is common sense). Still I guess it would be better to err on the side of caution with the 40, not like it's really going to lubricate any/that much worse right? And yes any tips to avoid LSPI are always appreciated, I just joined the forums and in the last week have read many of your previous comments on this subject and a few others. Thanks again for the info and welcome back!40 vs. 30 has nothing to do with startup viscosity; that number is the viscosity at operating temperature.
5W is the cold startup viscosity. You should use a 0W or if you don't want to risk voiding the warranty, use a 5W PAO oil that has a very low pour point value.
