hey came back on here to submit another question i had still have my 2005 Pontiac vibe from before and the new question i came with because I'm asking around even my facebook group related) said it would be fine my 05 Pontiac vibe base model with 130 horsepower from the 1zz fe engine wondering if its okay to use the 5w-20 oil instead of 5w-30 since i could then get instead of saving for it separately a oil filter and the 5 jug 5w-20 oil combo and since its the base model pure base no extras only thing I've done when i bought the car is add a new battery it does have an exhaust leak but its below my state so my mechanic said i could actually leave it like that and just take off the exhaust heat sheilds from time to time to stop the rattling and it will pass the smog test and i don't burn any oil here's what I'm getting at since i do not burn a single drop of oil because i even take it out on 1 hour drives and my mother has taken it for even longer to go to a relatives house to drop off my relative and the baby i have been getting mixxed awnser yes i can do it since its not the gt and even had a picture showed to me from toyota from a member on a post that the 1zz fe engine can handle the 5w-20 oil with the 5w-30 with mixing both out if i was to switch completly 5w-20 and i was hoping someone with a little bit more knawledge could see if its completly safe to do so since i am on a bit of a budget
Next time break up your long paragraph with punctuation. It’s hard to follow what you are saying. Thank you.
wondering if its okay to use the 5w-20 oil instead of 5w-30
What does your owner’s manual recommend?
According to your owner's manual only 5W30 is recommended (or 10W30 as an alternative in temperatures above 0 degrees F. if 5W30 not available).
• SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. However, if it is going to be 0°F (–18°C) or above and SAE 5W-30 is not available, you may use SAE 10W-30. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50.
It's a tough engine, you could use worse oil than 5w 20. But the right viscosity at high temperatures (the 20 or 30) makes the variable valve timing (VVTI on the cam cover, right) work properly, which will probably save you in gas mileage, as well as the wear and tear cost.
I'd bet you'd find a 5w-30 5 qt jug at a reasonable price - I have 2 in my garage, but you can buy your own.
so lets say its winter right since i'm gonnna keep using the 5w-30 for the summer could switch to the 5w-20 for the winter since thats when i get the most deal for my oil and its just my a to b currently
Use the GM recommended oil as described in the manufacturers chart provided by Chuck Tobias.
The engineers who designed this motor know best and they are highly paid for their knowledge and expertise. 😉
could switch to the 5w-20 for the winter
your engine runs at the same temperature regardless of season
Where are you shopping for your oil? I can find 5 quart jugs of 5W-30 all day long in every auto parts store and walmart around. It's not that GF-6B 0W-16 oil that only select new cars use.
That oil weight was popular for many, many years. You still find it specified even nowadays. My 1999 Ranger takes it, my girlfriend's 2017 EcoBoost Mustang takes it, even my 1979 Pontiac can use it if it's ridiculously cold outside. There's still a massive market for that weight.
autozone its the only thing near me rn and i'm not traveling an hour maybe 2 just to go somewhere else since the walmart here and other stuff i've seen since its the small version doesn't have alot of car stuff mostly just batteries and the other auto part store for cheaper parts is in another city so not worth it with these high gas prices even for using just regular 87 octane which is what i use in it everyday because when i first got the car along time ago from the orginal owner i've been puttig 89 in it to get it freshind up a bit since the old guy didn't drive it much and have it go at high speeds since i use it for highway travel sometimes and now i'll be using it to work when i go to autozone if i get this job since i'm also just generally searching for a job to make money
cheaper parts is in another city so not worth it with these high gas prices
I highly disagree, paying a few extra dollars in gas or individual bottles is well worth preventing the long term damage you'll be doing using the wrong oil weight, and the repairs.
Look for a technical service bulletin and see if Pontiac said it's compatible with 5W-20. I doubt it if it has variable valve timing. Ford did it with my 3.0 Ranger, I accidentally mixed up my 2017 V6 oil weight and the Ranger's (5W-20 and 5W-30) Ford said the 3.0 is backward compatible to 5W-20. The engine still used about a half quart more oil than 5W-30. It has no variable valve timing. It's just a basic pushrod, fuel injected V6.
You can buy jugs of oil on Amazon, or better yet, order it on Walmart's website ahead of time pick it up at the store. It's free. Your car and your wallet will thank you.
well on my engines hood cover which is the original says vvti so i assume it does because engines original tranny is original except i overfilled it a little bit with rilstone tranny stop slip since it goes through each gear just fine just slips a little bit so i poured some of that in and left it alone i think its about 0.5 overfull because i look at the dipstick it maybe 2 inches up on it maybe 3 last time i checked hasn't moved since and it still runs just fine now with that added in
