I was checking out Valvoline synthetic Maxlife in 5/30 and 10/30 flavors today. The numbers seem close to me. But I'm far from an expert. Any of you see an advantage of one over the other. The application is a Toyota 1GR 4.0 V6

Hadn't seen it on the shelf before. Figured why not give it a try. Engine is really noisy on it. But I'll give it some time.

Generally speaking....is there really a big difference in startup protection between 5/30 and 10/30? From what I can gather....5w is around -45F and 10w is about -39F. Both of those temps are well below anything we see around here. We see single digit temps here and there. But our winters are...

About a year ago I replaced the LCAs, sway bar links and outer tie rods on the ol' girl. Finally time to refresh the rest of it. The dampers were way over do. KYB Excels.....from The Tire Rack. Also threw on some new Autozone Platinum rotors. Been running a set on my Tacoma for 4 years. I...

I don’t claim to be an expert. In fact, I'm far from it. But hanging out here as certainly educated me quite a bit. Stumbled across this this morning. It seems to be filled with so much misinformation. It talks about synthetic oils being developed in the late 1990s, gasket conditioners...

Someone educate me on this measurement at 100°C I see lot when I'm reading oil specs. It's my understanding that the higher the number, the "thicker" the oil is at that temperature. So when reading about 2 different oils.....one is 10.8 vs 11.9 for the other....the 11.9 is the thicker oil at...

This thread is not necessarily meant to be too serious. Just a light hearted question. I have a '15 Tacoma 4.0 that I bought new 5.5 years ago....80k miles currently. Factory specs 5/30 and 5k OCIs....so that's what I do. Over the years it's seen mostly M1....vanilla, EP, Truck and...

Have a friend who sold a car that he used M1 0w-30 in. He gave me several quarts of it. Thought about using it for an upcoming OC in my wife's '19 Corolla spec'd for 0/20. Please, no flaming. I'm confident this subject has been beat to death. I'm not an expert on oil. Just a casual DIYer who...

I was doing some research on M1 High Mileage and Valvoline Full Synthetic with Maxlife...both in 5w-30 flavor. Problem is that all the thread I kept coming across were several years old. I tried to revive one to avoid cluttering up things with a topic that's probably been discussed many times...

I always feel a little silly asking an oil related question on this site because I'm sure most topics have been covered many times before. But here goes. What are people's opinions on using M1 High Mileage oil in a vehicle with 75k on it? I use it in my daughter's old Yaris without much...

Been using M1 in my vehicles for years with no issues. But lately I've been reading some good things about Penzoil Platinum. Thinking about possibly trying it in my Tacoma 4.0. Finding it in 5w-30 is not a problem. But finding it in 0w-20 for the wife's RAV4 hydrid has been challenging. If it's...
