question about gear oil

[drin21]

can i use other manual transmission oils with a different viscosity on my car? the manual specifically indicates SAE 75W-90. di paren ako nakakahanap ng mtf with the exact viscosity eh. ang inooffer saken ay iba ang viscosity. wala naman daw problema pag ganun. is it true?

What is the make and model of your car? Have you tried purchasing from the casa? You can buy the fluid there and have it serviced elsewhere to save on labor cost.

hi sir. mine is a 2007 Chevy Aveo sedan. my reason for asking outside the casa is because i want to try other oil brands like Royal Purple. my car has been using oil from the casa for 3 years now and i think other oil brands may give better performance. problem is, i haven't found a gear oil with the exact same viscosity (SAE 75W-90) as the one indicated in the car manual. auto supply shops and mechanics all say that i can use gear oils with a different viscosity as long as they are for manual transmission.

what do you think sir? ok lang kaya?

go ahead with the 75w-90 gear oil.

in tranny oils, what's more important really is the rating rather than the viscosity. if you don't go too far away from the recommended visosity range, you'll be fine.

if your manual recommends gl-4, stick to gl-4 or gl-4/gl-5 mix. pouring pure gl-5 rated gear oil will eat the soft metals in your tranny. you won't want that.

unlike engine oil (where sm is newer than sl, or ci-4 is newer than cj-4), it doesn't mean that gl-5 is newer than gl-4. for tranny oils, differeng ratings have different purposes.

for your car, gl-4, or gl-4/gl-5 mix, any viscosity except the extremes (75w-250 etc.) and you'll be fine. if you use the latter (or a higher viscosity) fuel consumption will increase. since your car calls for a lower viscosity tranny oil, you don't need 250's, etc.

hope this helps.

for tranny oils, rating is more important than viscosity.

use gl4 or gl4/gl5 mix if your tranny calls for gl4. using gl5 in a tranny that calls for gl4, and the oil will eat the soft metals. you don't want that.

you're good with gl4 75w-90, or gl4/gl5 75w-90.

you don't really need higher viscosity tranny oils. (140++ range)

hope this helps

Siguraduhin mo muna kung Gl-4 o Gl-5.

Kung grade II mineral oil o kaya semi-synthetic, pwede yung Castrol 80w-90 magkaiba yung packaging ng Gl-4 sa gl-5; kadalasan nasa Handyman o kaya DIY-shop.

Pwede rin yung Motul HD Gear 80w-90 pero mas maganda yung Motul Motylgear 75w-90, pwede pareho sa gl-4 o kaya gl-5; makikita mo yan sa True Value o kaya Ace Hardware.

Kung gusto mo ng fully synthetic, merong Royal Purple 75w-90 sa speedyfix o kaya Motul Gear 300 75w90 sa Autoplus along EDSA.

thanks guys for all your help. i get it now.

problem is, the manual does not specify if i should use gl-4 or gl-5 for my tranny. it only specifies the engine oil which is API SL (ILSAC GF-III) or better. i guess i should just use a gl-4/gl-5 oil like Royal Purple Max Gear.

gl-3, gl-4, or gl-5/gl-5 is fine.

not pure gl-5.

[speedyfix]

if you go slightly off viscosity wise like a 80w90 it should be fine.

the RP max gear 75w90 is just right for it though.

Pasingit ho, ano po bang recommended/magandang oil viscosity for AE92 4A-F Small body? wala kasi akong makita sa internet at wala na din ung manual neto samin.

[speedyfix]

75w90 is fine for that too.

[eatmylens]

75w90 is fine for that too.

Salamat sa mabilis na reply. Ilang liters kelangan and anung magandang brand?

[speedyfix]

you need around 2.5 liters so 3 na may konting sobra. we use royal purple in the shop for synthetic and castrol kung mineral lang yung budget.

Sir migs,

Ano ba recommend na gear oil para sa 98 lancer pizza pie?
Tsaka ano naman yung para sa differential?
Thanks!

[speedyfix]

royal purple max gear 75w90 yung gear oil. you car doesn't have separate differential oil and kasama na sya sa transmission.

[rushmore]

Ah ok sir.. ako yung nagpalit ng brakepads dyan last year mga sept. ewan lang kung naalala nyo pa hehe..

Baka pwede po paPM ng estimate kapag royal purple and regular gear oil lang kung magkano aabutin..

Pati na rin po engine change oil (RP at regular din) baka isabay ko na kaya pakisama sa quote..
Thanks!

[speedyfix]

ok

max gear is 800/quart and you'll need about 3 quarts.

oil change is still 2500 now.

you can call the shop sa number below for the price of the transmission labor and the price of our mineral gear oil.

thanks!

[rushmore]

Nagddalawang isip kasi ako sir sa RP dahil based sa nabasa ko sa ibang threads eh minsan kelangan daw magpalit ng orings o anything related kapag fully synthetic ang ginamit..

Kaya plan ko pa rin magstick sa regular oil para walang abala..

Same din ba sa gear oil na may adjustment din na gagawin?
